I was surprised to find the rating when I first checked it out, but I suppose it's a matter of personal experience and the taste that goes with it. I like to be reminded of my own personal experience (which is similar) and compare it to what the main character goes through in the movie. I suppose you'll like it if it means something to you, so if you've got issues with your past (relationships, particularly) and you like happy endings, give this film a shot. There's a bit of stereotyping in the film though, but they're presented humorously, so I didn't really mind. Besides, they aren't very damaging stereotypes (at least in my view), nor very annoying ones.
