Wonderful up until the last 60 seconds!
Unlike some, I enjoyed the ending with the fall/party etc (especially the 1st time), but even the 1st time, I never liked that he follows Christine out to her cab ride and asks to date her. She says he can tag along with her to the airport (how romantic!) and he says okay, ditching an entire party to pursue a girl that gigs all around the world and doesn't even know her own life story because she's that disillusioned by her own CRS creations.
I never felt that she was attractive or endearing. She manipulates him the whole way and yet he felt something for her despite acknowledging that he has no idea who she really is?!?! It's terrible. The last line of the movie is "would you like to have a coffee with me at the airport?"...really?
