I am a big fan of Aamir and loves his perfectionist attitude, but he disappoints BIG TIME in this movie. No flaws??? commercial movie at its best?? Well, forget about Aamir being perfect, this movie had flaws which one should not expect even in a normal movie. The concept of the short term memory loss was not explored even the least bit, the length of the movie was spoilt in useless scenes, the reason of Kalpana's murder was totally unrealistic as well, the fight scenes were a disgrace and looked as if it was SuperMan Returns remake in hindi in total south style. The acting in this movie is totally average(except Aamir, who was good,not great though). There were too many obvious mistakes in the movie to mention here, though the most obvious one was the climax where Aamir's character who should lose his memory in 15 mins, travels from the hospital to some place,fights numerous villians and after a LONG interval FINALY FORGETS!!! I think Aamir should have watched Memonto, not to copy it but atleast see how a movie based on short term memory loss should be treated. Bollywood makers should not pick up different and rare concepts if they cannot treat it right.
