This bad-scientist movie about bats that attack humans and the humans who track them—Texas sheriff Lou Diamond Phillips and zoologist Dina Meyer—is played straight, though it wasn’t intended to be taken that way. A colleague pointed out that the camp is supposed to come from the movie’s resemblance to older movies—parody by emulation instead of exaggeration. All I saw were unimpressive digital effects; artless, quick-cut abstracted gore; and a last-ditch attempt to evoke a visceral response by heaping the climactic scene with bat shit. Louis Morneau directed a screenplay by John Logan; with Leon.
