The title's relentless immaturity can grate after a while, though. Gruesome executions and grunted, testosterone-soaked dialogue sloppily plaster over the campaign's heavy-handed morality play. While the plot makes sense this time around, its clumsy mysteries are old hat to anyone moderately well read in science fiction. Still, finding bad things to say about Gears of War 2 is like trying to hate on the '07 Patriots. The game is impeccably engineered to dominate everything it sets its sights on, and yet ultimately falls short of achieving true immortality.
