In a bid to try something "different' movie makers experiment with several different ideas. This movie is kind of an experiment which as one of it's characters is kind of just an average. It reads like a diary and has a very simple and basic storyline - nothing more, nothing less. The basic premise is very Jab We Met but any other comparison to the original movie would be unfair. This does not match up.
There are a few moments in the movie that are really sweet and even touching so to say. The Goan school tour, the analysis of personalities and even Rahul's genuine reaction to Rianna's rejection.
The rest of it is somewhere between a tourism ad for Las Vegas ( in winter which is unique) and Goa. Every character is so definite in personality and diametrically opposite that it is hard to accept such exaggerations. Rianna and Rahul are opposites and so are their families, their backgrounds , lifestyle etc. They meet in a way that is possible only in Hindi movies and their relationship develops in a similarly unique and somewhat unbelievable manner.
This is a feel good movie so it is nice to watch it when you are low. Of course there is no significant story progression and it's more like a snapshot of two people interacting for a week. Many people have disliked the ending but to me that was the only honest part in the entire movie.
