I saw this Saturday night with a friend. Very well done, funny romantic comedy written by and starring Jason Segel, also starring Kristen Bell, Mila Kunis, Jonah Hill and Paul Rudd. As far as I'm concerned, another success from the Apatow gang. Segel gives a great performance--he's just a naturally likeable actor, plus he gets to show some musical skill and...other assets, too! Kudos to a guy willing to do full frontal in the name of comedy, and it actually made for a good full circle element to the story. I also admire that he gave the ex-girlfriend some dimension (I hate when they're depicted as total shrews because it makes you respect your hero(ine) less, like Why was s/he ever interested in this person?), and even her posturing rock star new BF ends up kind of appealing. I always thought Mila Kunis should be a bigger star, and hopefully this helps her a bit. I don't imagine this will be a megahit, but it's a very worthwhile date movie that will not disappoint either party.
