I have watched it because it has received a lot of awards so my expectation was very high.
I think this movie is way too overrated. The cast is overall good, the story is well written since we can clearly see the difference between the rich and the poor, the movie draws a clear separation between the two and illustrates how difficult it is to cross that separation for both of them. For the music, I think it was too simple, it did not attract me.
I would not recommend this movie to be honest. It is a little bit too weird and the start is too slow which makes the movie a little bit too boring. I wanted to skip many parts because I felt it was too slow. In clear words, I was disappointed. The last 30 minutes were better.
