I haven't watched any 'Girls' yet, but I think I'll have to now. I think this film hit a bit too close to home at times, definitely can relate to the main character a lot and I'm not sure if I like that. :--D It got a bit flatter towards the ending, but still a good film.
I think people are being a bit harsh giving this only one star or even less. Sure, it didn't change my life in any way, but it was still a perfectly watchable, even if predictable, film. And Emily Blunt is always cute.
