As much as I love Siddharth and want to like this movie, I can't.
Where do I even start. The fact that a forensics can't even guess the amount of material in a pill by weighting it when an average person like me easily can, or the fact that in each of those stories he is hit in a different part of his head and by a simple test they could've found out who's telling the truth or finding out that Shekhar was his wife's lawyer just needed a few questioning of the acquaintances which they didn't, or maybe the movie's tryina mock the police and their inadequacies!
Plus the twist was way predictable, it would've been way better if he had killed his own wife and the woman had killed the husband but one got locked up and the other got away.
