Slither appears to be one of those campy, good-natured gross-out horror flicks about which the internets tend to get very excited - and, as someone who is looking forward to Ultraviolet, I am certainly not in a position to throw stones. The film stars Michael Rooker, Elizabeth Banks, and Firefly/Serenity's Mal, Nathan Fillion, and revolves around "A small town [that] is taken over by an alien plague, turning residents into zombies and all forms of mutant monsters." Based on the footage in the latest trailer, the plague is mostly a lot of slugs, and the main mutant form is, well, slugs with teeth.
