Finally got around to watching Battleship and it isn't as bad a film as I was expecting, having said that I'd already seen the Asylum Studios knock off version (I blame insomnia). The plot is the pretty much bog standard screwup brother comes into his own during alien invasion cliche although the scene where he is trying to woo the woman with a burrito scene did strike me as something that Nick would have done.
The tie in to the board game is cleverly done and I suspect that younger kids won't have realised it when it was happening.
While not at the top of my recent film list (Dredd 3D), its something I'd probably watch again.
