Darling starts out seeming like a good but fairly throwaway 60s-sweetie-who-plays-around film, but then it delivers a good bit more. I really like Dirk Bogarde. Good cast.
If I say this film is not worth the fuss that surrounded its theatrical run, please don't take it the wrong way. It's still good and funny, especially for what it is. And all the cameos are undeniably fun. Unmistakably Apatow. The ending is a little too much, but what else could I expect?
