They don't actually sink the battleship. But that's ok! I just wished a cruiser and a submarine had gotten some action too. The destroyers hogged the show. I mean, I know those pesky two-pegged fuckers are hard to hit, but still.
IN CONCLUSION: Battleship is by far the best war/alien invasion B-movie based on a board game whose first plot point revolves around a burrito that I've ever seen.
