Plot The slumbering Southern town of Wheelsy becomes the focal point of an alien invasion when an extraterrestrial parasite crashes to Earth and possesses the town bully (Rooker). As the alien’s spawn turns the townsfolk into zombies, chief of police Bill Pardy (Fillion) sets out to turn the tide.Verdict Undeniably funny and gooey to boot, Slither may not be groundbreaking but it is a rarity: a horror-comedy that does both its genre-parents proud.
