I don't loathe Valentine's Day -- I just loathe the pressure placed on people. Buy a single rose, if you must. Buy an Otis Redding album (always do that). And watch a movie, preferably a movie in which romance goes terribly awry -- like Vertigo.
Given the track record of director Shawn Levy, I approached Date Night with a certain amount of dread -- OK, a lot of dread. So let me say straight off that Date Night isn't terrible -- and I mean that as the mildest of praise.
