I don't really like Pine as Kirk but its mostly the script.
I'm hoping he'll come off less of a jerk in the next movies. I certainly liked him better in STID than in ST09.
Come to think of it I didn't like Shatner as Kirk until the 80s. I thought he was too much of a 'ladies' man.
Maybe in another 20 years I'll think better of Pine.
I think I'd like Urban better as Kirk though.
