I'd never heard of this but really enjoyed it.
I'm a film buff who has his finger on the pulse, and yet I'd never heard of this. Thursday I got an e-mail from AMC offering me two free tickets to see it. Being a big fan of both Sam Rockwell and Chloe Moretz (and no strong feelings one way or the other for Keira Knightly), I decided to cash in that free ticket and see the film. What a pleasant surprise.
This film was charming, and amusing. It had good performances, and the characters were all mostly likeable (well maybe not Ellie Kemper. I loved her on The Office, but her character was so unlikable!!)
I'm not sure if this is worth going out of your way for, but it's worth seeing. I dug it.
