As far as comedies go, this is definitely one of the better ones. The actors are great, the story is fun and interesting, the location is new and fresh and the emotions feel genuine. It's just one of those movies that you watch to make yourself feel happy. It is not, however, a movie that you put on to learn about how real life works. There aren't really any useable lessons about breakups in this flick, nor are there any real lessons about relationships: it's all about the entertainment, so it sticks to predictability. Despite that, it never feels stale or "factory-produced", much like Knocked Up and The 40-Year Old Virgin.
Only one real solution for dealing with breakups is ever given (other than "be lucky", I guess), and the rest of the film is based around building up motivation for it. The solution? Go out and do something!
In a sentence:
A top-notch comedy that is very motivational, funny and entertaining. Having actors like Bell, Curtis and Segel certainly doesn't hurt either!
