No, Jaime wasn't THAT pretentious, but the fact of them being writers/in the arts, the connection to the museum of Natural History (can't you just say Jaime and Cathy's kids connecting to it that way?), the arguing over success, the cheating people in their little circle...and I would think Jaime and Cathy's kids would be just as screwed up as the two in the movie.
I really enjoyed the film - I would definitely say it was one of the best examples of how to write character I've seen - in 80 minutes you really felt like you knew so much about those people and their dynamics -- again, much like Last Five Years.
Hi, Shirley Temple Pudding.
