This movie, directed by Barry Levinson, is constructed like a documentary from "found" footage. There's an extremely irritating news reporter who narrates the movie, which is a collection of TV media footage/home camera/iphone/police video, et cetera, about an infestation of mutated isopods (what Pill Bugs are) that have contaminated a coastal Maryland town. Some of the scenes are effective, such as when a group of divers encounter the carnivorous isopods off the coast--and another, when a hospital is overrun with infected people. But I found the execution lacking.
