Giant monsters from the deep are destroying cities, but instead of just blowing them up from a distance, the world unites to build giant robots to engage in hand-to-hand combat. This is a cross between old-school Godzilla and a variation on Transformers, but to enjoy it you must be willing to accept director Guillermo del Toro’s imagination. The effects are exceptional and the action is pretty cool (although sometimes confusing). The trite attempts at character involvement only serve as padding between the battles. This movie is all about the fights and del Toro’s vision, so don’t expect more and you’ll dig it. (Stay thru the early credits for a punchline.)
