At some point over the last few years, the cynical and bitter won Valentine’s Day. Resenting and deriding it as a greeting-card holiday eclipsed most good will and chocolate eating. Well, the National are here to reclaim the holiday with “I Need My Girl,†a song lead singer Matt Berninger wrote for his wife. To heighten the message is a truly stunning video of couples intimately dancing frame-by-frame, in slow motion, in front of a black background. It might be cold outside, but at least your heart will be warmed for four minutes. Sure, that’s cheesy — deal with it. Happy Greeting Card Holiday!
