That's the kind of evening I could easily find a slot for every week--a leisurely get together about 30 minutes before the movie starts, chuckling together during the film and a little tweeting afterwards.
Cyrus gave us the impression of being hilarious, and while there were many laughs sprinkled throughout, it was more of a cautionary relationship tale with a happy ending. My favorite part, were the characters and how they came off together on screen. All of the characters (with one exception) were likable, real people.
I characterize a good movie as one that holds my attention throughout and never makes me say, "um, riiiight! as if that would ever happen!". The story has to hold me and this one did.
