Everyone who doesn't like this is a tetrist.
Seriously though, say what you will about that Battleship garbage, at least it had actual action and a pseudo-storyline to go off: two different teams of ships don't like each other, they duke it out. The only way I can see this "working" is either A) a Pixels style romp in which actual Tetris blocks are crushing everything on Earth, or B) an incredibly meta and pretentious thriller in which Tetris blocks are code for something entirely unrelated.
