Battleship – It may be based off a game, its actual ties to that game might be a little… tenuous, and the "I believe" button-whacking may have been hard and fast*, but you did not really think about that during the movie much, and damned if it was not exactly what it was advertised to be – a delicious-computer-graphics-filled visual orgy documenting the United States Navy kicking some unfriendly aliens’ ass, and I can live with that.
(On a somewhat related note, does anyone know if any of the Old Guys who materialized out of the woodwork on the Missouri were really part of her original crew, or any BB’s crew? Because that would just be awesome.)
