Great movies about couples that break up are rare treats. After all, few viewers are willing to invest two hours rooting for a fictional relationship and then be disappointed when the two main characters can't work things out. Accordingly, happy endings in romantic comedies are pretty much guaranteed. The couple falls in love, overcomes some sort of obstacle, and eventually walks off into the sunset.
It can be incredibly refreshing, then, to stumble upon a movie that does not completely follow the normal formula. Indeed, realistic love stories are rare but welcome; they teach great lessons. You even learn something about your own relationships if you watch. Maybe happily-ever-afters aren't so important after all.
