Form - The film's all over the god damn place. I wouldn't be surprised if five different people directed half the film.
F/X - There are a lot of great gore effects, including heads popping off, eyeballs falling out, and organs being removed.
Acting - I don't know if the actors can be blamed for how terrible their performances are. I mean, Bruno Mattei could have fired them once he noticed how ridiculous half of them were. There seems to be a huge focus on actors with terribly exaggerated mouth movements, which is sort of fun.
Mise en scene - Nothing terribly unique, especially considering the over-the-top "you've never seen anything like this before!" quality the film desperately reaches for.
Quotables - At one point, one of the film's characters suggests that a tall black zombie might be a leprechaun.
Cool stuff - Great effects, idiotic writing, editing, and everything else. My favorite long take: after schooling all the zombies throughout the film and being totally on his A-game killing them all, one character randomly starts playing with a broom like it's a guitar and singing dumb songs. Out of nowhere, four zombies randomly walk into the frame and start eating him.
