I absolutely didn't understand why this film was so much talked about. I admit that few portions of it were good. But it didn't make any sense towards the end. It definitely didn't have to end that way. After the movie, I immediately wanted to forget it. And I have watched lot of great films with sad endings. The feeling this movie gives at the end, is a not a feeling I want to carry ever.
Also, to be frank the main lead girl's acting I didn't like personally. So, only 1 star from my end.
