“Slither” is a hilarious take on alien body snatchers and zombies.

Set in a small, po-dunk town (as they tend to be), an alien invader takes over the body of a local and attempts to assimilate the human race with fat, red space-slugs. This is a lot more amusing than it might sound, but be warned, it bears no resemblance to Men In Black. Directed by the same man who brought us the 2004 Dawn of the Dead remake, Tromeo and Juliet and Sgt. Kabukiman’s Public Service Announcement, there are bound to be some disturbing images and a gross overuse of dirty words.

“Slither” is indulgent with its horror and its comedy. As Boston Globe reviewer Ty Burr put it, Slither is “knowingly in touch with its B roots.”

The characters are more or less one-dimensional and stereotypical, such as the sleazy, self-concerned town mayor (Henry) who screams at the quiet, yet masculine sheriff (Fillion) to fix everything without offering any real help. The monster itself is more reminiscent of the creatures you would see in 60s and 70s horror, than the sleek, vampire-ish monsters of modern horror.

All of these elements come together to give the feel of early Romero-esque film-making.

This film is not for the block buster types, the weak of stomach or the easily offended. But, for all the true horror fans out there, this could be the best $8 you’ve spent on a theatre ticket in a long time.Good Night, and Good Luck is an outstanding
