Good concept spoiled with bad acting and bad writing. Illogical sequences makes the movie more cinematic and that in itself doesn't allow the audience to connect with the movie.
It's difficult to give a bad review for a movie which was taken with good motto. But at the end of the day a movie is an amalgamation of several crafts and one had to do justice to it.
Bottomline: A very good concept spoiled with bad writing, bad acting and bad sequences.
