Saw the film on Friday, thought it was great. Not Smith's best film (Amy) but was a really, really good film. I laughed a hell of a lot during some of the dialogue (I've always laughed more at dialouge than set peices) and it was great seeing Jeff Anderson back up on the big screen. Thought the chemistry between Rogen and Banks was awesome and the support cast was also really funny.
If I had one complaint, the film felt kind of rushed during the "idea through to casting through to getting ready to make the film" montage. But maybe it won't feel that way after I watch it again.
