Think of This Means War as a Valentine's Day leftover: a droopy love triangle seriously short on sexual chemistry, not to mention the kind of playful self-awareness that can spice up even the blandest romantic comedy. Doesn't help that the principals in this improbable contretemps—CIA agent best buds and partners fall in love with the same woman—come off as attractive androids programmed to act funny and charm the groundlings.
