Horror Movie Review: Serial Rabbit One (2025)

Released in 2005, Serial Rabbit was a horror comedy directed by Brett William Mauser, who wrote the story with Bradley Bates. A film about a manic in a bunny costume going on a killing spree in San Antonio, Texas. It, and its sequels, have become something of a cult classic.

This is not a review of that film. Well, technically it is.

You see in 2025, the original film was modified and updated. Returning with new music, effects and additional scenes. I guess this is closer to Brett William Mauser’s true Serial Rabbit vision?

Now, I’ve never actually seen the 2005 original so I have nothing to compare this version to, but if this is the updated and modified version, I really don’t want to see how bad the original looked and sounded.

Serial Rabbit One looks and sounds atrocious, has a laughably basic story that is stretched so thin that you can see right through it, and lacks finesse at every single turn. Yet, even though it is recognisably awful, and not a recommendation at all, I have admit to warming to it as it went on.

This isn’t a film that you should take seriously at all, and if you keep that in mind, you will come away having enjoyed it that little bit more. Especially as everyone involved within the film certainly wasn’t. What they were all doing was trying their hardest to make the film entertaining, and in some ways, they deliver. You can’t help but root for people throwing their all into something, even if the result is still an absolute turd.

So, effectively, the film plays out like an anthology with the costumed killer, now in the hands of the police, telling two detectives about his crimewave. Don’t ask why he’s not in cuffs, or why he is still in costume, or why he communicates with sign language. It’s Serial Rabbit, what more do you need to know?

Actually, the bits in the ‘police station’ are some of the best bits as far as comedy goes. A scene where one detective runs down a ton of different ways to describe sex managed to get a snort out of me.

Alas, by comparison, the horror aspects of the film are sorely lacking. Uninteresting kills and bad effects (updated or not, they still look terrible), those hoping for a gory and violent rampage will come away disappointed. I certainly did and when coupled with the egregious problems elsewhere, such as a boring story, no characters, shoddy acting, and a cheapness that is hard to overlook, it should be clear that this is one to avoid.

Unless you’re like me and you want to run through this series and see just why it’s considered a cult classic. A ‘so bad it’s good’ film? Not in my opinion, but I can see why some might rate it that highly. Let’s see what Serial Rabbit 3: Splitting Hares has to offer (there are no even numbered sequels).
