Blue Valentine, the film that EW’s Oscar expert Dave Karger has referred to as an “utterly devastating, completely believable marriage drama” that should earn stars Ryan Gosling and Michelle Williams their second Oscar nominations, just received an NC-17 rating, but you’d never know it from the trailer below. I haven’t been this quickly sucked into a movie couple’s relationship since the (500) Days of Summer preview. It’s partly because Gosling and Williams are as likable as Joseph Gordon-Levitt and Zooey Deschanel, but also just because you can tell the characters are unique, fully developed, and capable of ripping your heart out because you were so instantly invested. Watch it below.
