There have been a lot of games converted into movies, most of them have been science fiction, and a lot of them have been bad. Somehow I never visualized the classic board game (later adapted for the computer) Battleships being turned into a movie, nor would I have expected it to be sci-fi. And yet, it appears both of those things are true, at least as far as their first trailer for the film is concerned (some, like Topless Robot, disagree with this conclusion).
