I don’t know if the first zombie date flick is a step forward or backward for civilization as a whole, but I can say that “Warm Bodies” pulls off a pretty impressive trick: It has its “Twilight” and goofs on it too.

Based on a novel by Isaac Marion, it’s a post-apocalyptic star-crossed romance, complete with neo-Shakespearean balcony scene. Over in this corner of a nameless metropolis (Montreal, doing a fair impression of Manhattan) are the remnants of human society, bossed over by survivalist Grigio (John Malkovich) and hoping to rebuild behind a massive steel wall. Out at the airport — and everywhere else, apparently — are legions of the undead, shuffling blindly through their endless days like commuters who’ve forgotten where they live.
