The type of B-movie I always enjoy watching: gory, silly, tongue in cheek, and completely over the top in every respect. The opening set-piece is by far the best part of the movie (and the surprise cameo helps too) so if you like that then you'll probably enjoy the rest of this one too. Goldberg is a good choice for a genial villain, the FX are cheesy but fun, and seeing old-timer Robert Culp getting involved works too. Obviously if you're not a fan of trashy horror you're not going to like this one, but I thought it was quite decent.
