First of all, just because it is an erotic drama doesn't mean one should compare it to the fifty shades trilogy. They're both different in many ways and should both be kept separate.
The movie has succeeded in getting the attention of the viewers. Be it the posters or the controversial comments, it is now being talked about. If you are into romantic genre and don't mind a bit extreme scenes, you'd want to watch it at least once.
Despite having a strong base for story line, the movie somehow fails to build the story with time. More scenes focusing on the actual story were expected.
Instead, most of the scenes are trying to build up the chemistry between the lead actors. Speaking of which, the protagonists are both strong characters which are played quite well by the respective actors.
All in all, it is something different from the usual soap-opera like romance movies and I recommend watching it for once.
It has the required good music, nice filming, hot actors, exciting content, what else do u want?
