Seems like the first half of the movie and the second half of the movie are directed by two different directors.
I liked the cinematography. Nice locations. The drone shots were very beautiful.
I liked the 'Amar bhul hoye gechhe priyo' song, but the background score was not so good, in my opinion. Rajlokkhi's song as the Baiji was quite out of tune sometimes, I do not know whether that was intentional.
Best thing about the movie: Rahul. I can watch the movie once more only to enjoy Rahul's performance. Though he had to follow some stereotypes like "the pose one sits in while listening to a Baiji while sipping whiskey", his calm but rowdy attitude, the way he asked for the 'shovel' in the end, demands for appreciation. A big Shout out to Rahul.
Worst thing about the movie: The twist in the climax. If "that" had to happen, all those 'Rajarhat flat' incidents become unnecessary. I know that it is 'what is' Vs. 'what could be', but I think, the merging between the two realities was shaky and somewhat unsuccessful.
The DOP, Rahul, and a few facebook posts managed to turn the movie into a somewhat good movie, which does not live upto the hype it recieved.
