Movie Starts on a great note, but looses steam in between. The director could have done something about this. there are scenes in between, why you start feeling the protagonist is acting in the movie. Its a good movie no doubt, but i was comparing this to all time classic musical hit "The Sound of Music". Director should have retaken some scenes to have a smooth flow between the events.

for ex, the way Mia ditches her ex makes no sense. She just runs away to see a movie with a new guy ? crazy. Sebastian is having dinner with Mia...the dialogues look so forced on to the audience :(

compare the other romantic movies...the notebook or 50 first dates. The "feel" that you get after watching the movie...it stays on for few hours. I liked the idea of the ending, but again, looks very disconnected. 5 years not in touch ? what came in between them for those 5 years ? ego or plain interest lost between them ? don't try to pull a Nolan here.
