What parents need to know
Parents need to know that Battleship (inspired by the classic Hasbro board game) is the kind of summer alien adventure that, like Independence Day, features a doomsday alien invasion that only a select armed forces group can fight against. As you'd expect, there's a high body count -- mostly due to all of the building- and ship-destroying explosions that the aliens -- though not much gore. Many high-tech weapons are used, one female character dresses somewhat suggestively, and the language can be occasionally salty -- "s--t," "bitch," and two cut-off exclamations of "motherf--er." Although the effects-heavy action is filled with scenes of targeted violence, there are ultimately some positive messages about rising to the occasion and overcoming your fears.
