Keke Palmer was fun in that movie, but from what, admittedly little, I've seen of her she seems to have been playing herself.

I think they were all clapping not because like "oh my god we agree you have changed our lives urrrrrmagherrrrrrd" but out of appreciation of a well rehearsed and delivered short history.  Like an appreciation of a performance.  That didn't seem that weird to me, they're supposed to all be movie people.

I kind of agree about tone, but I dunno.  It was an interesting new take on a familiar concept.  I liked the new (at least to me) concepts.  The story with the Asian guy and the monkey was great too.
