Bruiser was panned by many horror fans upon its release, mainly because it was directed by Romero and usually gets thrown into comparison with his other works, most notably his popular zombie movies. Obviously, this is not a zombie movie, it borders along being more of a thriller than an actual horror movie and I guess fans of his just didn't like such a drastic genre transition for him.
Anyhoo, I have always enjoyed this movie. It's by no means perfect, the acting at times is a little hokey, sometimes Jason Flemyng sounds as if he's trying to deliver lines more poetically than they actually are, but at least the story is different to most other movies out there. We get to see a genre favourite, Tom Atkins, play a detective in all of his typecast glory and Peter Stormare just goes balls-out weirdo in his role. If you pause it at the right time, you can even see Stormare's cock during his first scene in the movie... ummm, don't ask me how I came across doing that.
The movie also features a cool setting for its finale which treats you to a live Misfits performance which goes for quite a lengthy period of time. You can hear multiple songs of theirs being played, one of which gets looped way longer than it actually runs for. But hey, you can't complain when a horror punk band of their stature is featured like this.
Bruiser could have been executed and acted better, but it is interesting to see Romero take on a much different type of movie and I think the overall product serves well enough for the type of movie that it is.
