I just loved it, seriously. What is there not to like in this? Plots were such like, i completely got dipped in to, forgetting as to what happened in the previous scenes, and eventually it would connect in the end, that makes us rethink previous scenes. Climax is just excellent. Moments where flashback scenes were being shown, here also, one would entirely forget the current situation and flow in the flashback that is shown, leaving one with mixed emotions. I never experienced such a movie. Great job done. So satisfying after watching, somewhere i felt movie should not end and should keep on going. Classroom humor scenes were so good. Literally, i laughted to death. Still trying to figure out the overall rating this flick has got. Why???!
