1. On the whole I enjoyed it. I liked the fact it was a pretty ambitious film and, whilst obviously fitting into a genre, wasn't necessarily predictable and didn't go for obvious/easy happy endings.
2. Parts of it really annoyed me though, as is often the case with Judd Apatow's films. I think the reason for this is because he always wants to have this improv. stuff in there which is presumably supposed to show how funny the actors are when being spontaneous but, on the whole, actually shows they're not all that funny without a script put in front of them. It wasn't quite as bad as the scenes with the guys hanging out in Knocked Up but was weaker without it Also it was over-long.
3. Seth Rogan was good. I think the fact I find him really likeable is what carried the film and I thought the stand-up scenes worked well.
4.Credit where credit's due Adam Sandler was good too actually, come to that.
5.And Eric Bana lifted the film when he showed up.
6.Meanwhile I quite like Jonas Hill but also think he's the worst perpetrator of bad improv./thinking he's significantly funnier that he is which is the films biggest flaw.
7.I wasn't entirely clear why we were (presumably) supposed to be rooting for Seth Rogan's character to get together with a girl when it was evident he was ridiculously uncomfortable around her and they didn't really have much in the way of a spark/compatability about her. I think we were supposed to like her because she was a bit geeky and quirky looking (and I imagine looks-wise she'd be many indie boys' wet dream) but that didn't really make up for the fact that there just wasn't reaily much between them, especially compared to Sandler's relationship with his ex. To be honest it just made me wonder why people (me included in the past) spend so much time chasing after people when it's evident they aren't really suited to each other, which I don't think is what I was meant to think.
So, anyway. 7/10. Would recommend watching but might not stand up to repeated viewings.
