This is a girl show that could have done with about 72 less eff words. While I liked the quirky characters and their humor (somewhat Wes Anderson-ish), this film wasn't good enough to forgive the "chick-flick" formula it unabashedly clings to. I didn't really understand or agree with the motivation to include an onslaught of profanity for 2 hours.
DeNiro was amazing, as good as I've seen him. The other performances were also good, and the screenplay oozed with personality and charisma.
If you're big into chick flicks, and I mean really big, you may want to see this. Otherwise don't waste your time. Kids should avoid this at all costs.
