I Am a Hero (2015) – A horror movie review a day Halloween 2025 - October 28th
Welcome to Knockout Horror. It’s day 28 of our 31 days of Halloween 2025 movie-review-a-day feature. The zombie genre, quite literally, rose from the dead back in the early 2000s. After a decade of virtually nothing, all of a sudden, shambling was cool again and the horror world started to appreciate how much they had missed the un-dead. Ever since then, we have seen an enormous amount of zombie themed genre films. One such example that appears to go a little bit under the radar of fans is the J-Horror movie we are looking at today – I Am a Hero (Ai amu a hîrô, 2015).
Dead and Buried? The Zombie Wilderness Years
To actually appreciate where we are at with zombie themed horror movies, you really have to look at the period from the mid 80s to the 2000s. After George A. Romero’s Day of the Dead (1985), the genre was, excuse the pun, limping along. The demand for zombie movies had all but evaporated.
The undead were seen as an unwanted example of a bygone era where horror was far cheesier and much less scary. Most zombie features were doomed to haunt the straight-to-video sections of rental shops. The most noteworthy release of that period might be Michele Soavi’s Cemetery Man (Dellamorte Dellamore, 1994); a movie which, looking back, felt way ahead of its time.
Peter Jackson’s gonzo horror Braindead (1992) deserves special mention but I’d argue it wasn’t so much a full blown zombie movie as simply a crazy comedy. You could actually make the argument that the era’s most significant zombie related media wasn’t a movie at all.
The video game Resident Evil released in 1996 and offered us a brief hint of what was to come in the not too distant future. It reminded us that, when handled well, the genre can still be scary. Still, it was the dark ages for the undead and a resurrection seemed unlikely. Something needed to change and drastically.
Back from the Dead (And Faster Than Ever)
As I am sure the vast majority of you know, something did change. Danny Boyle came along in 2002 with his seminal hit 28 Days Later and introduced the world to Fast-Zombies. This was an entirely new breed; there was no shuffling or ambling here.
These zombies were ultra rapid, ruthlessly capable, and full of rage. A brisk jog was no longer sufficient to outrun this version of the walking dead and Idiot Plots just wouldn’t suffice. If characters were to survive, they would have to match that speed and aggression to be in with any chance. Zombies were finally scary again.
Zack Snyder joined the fray a couple of years later and blew the mall doors right off with his Dawn of the Dead remake. This movie brought together the old and the new. Combining fast-zombies with the more traditional style and it proved to be the zombie outing that much of the mainstream had been waiting for.
Shaun of the Dead also released that year, introducing the world to the rom-zom-com and the rest is history. The undead have been en-vogue ever since. The horror world has seen the release of enormous hits like REC, Zombieland, Warm Bodies, Train to Busan, and many more. One such movie that doesn’t seem to get the attention it deserves is the one we are looking at today – I Am a Hero.
A Hero Down On His Luck
I Am a Hero follows manga artist assistant Hideo Suzuki (Yô Ôizumi). Down on his luck and frequently losing himself to elaborate fantasies of success and achievement. His career is floundering and his girlfriend is, frankly, sick of his shit. Kicked out of the house, he wanders the streets.
Reports of a mystery virus spreading around the population seem to be getting too close to home as his workmates become sick. Little does Hideo realise, things are about to get a whole lot crazier and, this time, it isn’t all in his head.
I’ve actually been meaning to check this movie out for quite awhile but never got round to it. I have mentioned it a fair few times on our sister site, Ranking Horror, where I have touched on quite a lot of zombie content.
It was actually a suggestion from Darren at The Undead Symphony Podcast that prompted me to make I Am a Hero part of my October movie-review-a-day feature. Huge thanks to him for taking the time. Definitely go and check out that podcast if you are fan of all things Zombie related.
Zero to (Maybe) Hero
Based on the Manga, written by Kengo Hanazawa, of the same name, it goes without saying that we already have a pretty established character and story here. The film version does deviate from the source in a number of ways but this is pretty standard for film adapatations.
Hideo is a hapless individual. He has never achieved anything other than a participation trophy for his work. Despite that, deep in his mind, he believes that he can be a hero but has never had a chance to prove it.
That opportunity is thrust on him after an outbreak of a virus which turns the residents of the city into mindless zombies. Somehow, he manages to avoid becoming infected before meeting up with a high school student called Hiromi (Kasumi Arimura).
Together, they begin a harrowing journey to Mt Fuji where they believe the virus can’t survive. This narrative forms the crux of the story. It’s part road trip and part ode to Dawn of the Dead when our protagonists finally make their way to a retail district housed by a group of survivors. For the most part, it’s your standard zombie horror fare coupled with a few laughs.
Hideo isn’t exactly a compelling protagonist and his inability to push past his overwhelming anxiety can make him a frustrating character. It seems as though some of the more interesting elements of the manga have been cut, too. Still, for fans of zombie movies, you will probably feel at least a little comforted by how familiar it all feels. His growth towards the end of the film is quite satisfying, as well.
Guts, Glory, and Great Zombies
Needless to say, the story isn’t where this movie shines, it’s in the action. The city is in absolute chaos and this is one of the areas where I Am a Hero really comes into its own. Much of the carnage takes place practically rather than via CGI. You have cars crashing into each other, people being run over, zombies munching on unsuspecting citizens, and Hideo at the centre of it all trying to escape.
It’s legitimately impressive stuff. Something about the sheer number of extras and practical approach to the action makes it feel so much more impactful and authentic. I Am a Hero retains a level of realism that makes it seem almost feasible. If this were to happen in real life, it would probably look a lot like this.
The infected aren’t just your typical zombies, either. Sure, they love to much on people’s arms and they look fairly standard. But they actually retain some knowledge of who they were before. This causes them to become stuck in a repetitive action that reflects what they did in real life on a day-to-day basis.
One is attempting to continue shopping, for example, another is repeatedly doming himself by trying to Fosbury flop while practicing high jump. Their focus on these tasks is only broken by their overwhelming desire to kill and eat. It’s a fascinating way of adapting an altogether too familiar trope.
Balancing Zany Laughs with Brutal Gore
The comedy, obviously, plays centre stage, too. It’s fairly typical of zany Japanese movies and if you are a fan of that you will feel right at home. I, personally, am so really enjoyed that element of the film. I really appreciated how daring I Am a Hero was when it came to finding a balance between the laughs and violence, as well.
It’s not just a comedy; that’s only one part of it and the laughs frequently take a back seat. It can be occasionally quite deep, is frequently action packed, often fairly touching, and even a little bit sad in parts. It’s actually a pretty damn violent and grotesque film that’s far more graphic than you might think, as well.
Most zom-coms tend to keep these elements to a minimum. Perhaps concerned that too much gore will put off fans who are here for the giggles. Director Shinsuke Satô shows no such apprehension. Heads are popped, arms are pulled off, teeth are knocked out. This is a movie that is actually pretty wince inducing, in parts.
The practical effects look utterly fantastic, as well. I wasn’t a huge fan of the transformation sequences but everything else is absolutely stellar. Special shout-out to the physical performances of some of the actors, too. It’s utterly incredible and always a feature of Japanese horror that feels extremely special.
Dragging Its Feet (Just a Little)
There’s a distinctly video-game like feeling to a lot of the action and violence. Certain scenes are very reminiscent of the zombie game Dead Rising. You have never seen zombie heads popping in such satisfying fashion outside of the Resident Evil games, either. It’s awesome!
There are issues that deserve mention, of course. I am not sure why Shinsuke Satô thought a two hour plus runtime was necessary. It doesn’t exactly drag its feet but it is definitely a bit on the long side of life. The violence might be a bit much for some people, as well. Especially if you are here for the laughs.
Some are probably going to find Hideo difficult to like. He takes a long time to actually develop and, for the most part, feels like a woefully incapable protagonist. He really needed some quicker growth but I guess that is just part of the story arc.
I think viewers who are used to Western horror might find some of the production values a little lacking. This is just a cultural thing, though. Japanese horror rarely has that shiny veneer that Hollywood horror has. It is far more gritty and raw feeling but that adds to the enjoyment, in my opinion.
Should You Watch I Am a Hero
I Am a Hero is one of the better zombie comedy horror movies of recent years and a definite underrated gem. It’s legitimately funny, the action is intense, the practical effects are utterly fantastic, and the story is engaging enough to act as a decent vehicle for the carnage. It’s a bit long and some might find the protagonist a bit unlikable. Some might not appreciation its distinctly Japanese take on a very Western genre, as well. With that being said, I had a great time with this and thoroughly recommend it.
Our Scoring Philosophy: A Fair Fight
Horror is a genre that thrives thanks to indie film makers and low budget creators. At Knockout Horror, we firmly believe that every movie that we review deserves a fair fight. That's why we grade on a curve. Our star ratings are all about context, judging a film on what it achieves with the resources it has.
A 4-star rating for a scrappy indie horror made for $10,000 is a testament to its ingenuity and raw power. A 4-star rating for a $100 million blockbuster means it delivered on its epic promises. We don't compare them side-by-side; we celebrate success in every weight class, from the back-alley brawler to the heavyweight champion. Please keep this in mind when considering star ratings.
