Over all it was a bit of a disappointment. Onkara and reviews had raised expectations a bit, and I'd say it was a bit of a let down due to that.
It has its moments of brilliance, but I really found it uneven. It would start to get interesting, and then suddenly there were rather bollywoodesque slow scenes/concepts and then it had to start all over again.
However over all , if you forget the weight of expectations, and the rather irritating ending, and the tributes to bollywood, it still is a pretty fascinating movie.
