Manu is a must watch film.The suspense was well kept till the end. The twists were good. The plot was too good. The only drawback was the length and dialogues. But when you think all over again, I couldn't find a single scene which could be removed. Every scene had a connection and the dots were well joined. So the only thing u might find odd are the dialogues in the second half but again if I recall the dialogues after the movie they had deep meaning, you would definitely relate to at least one of them. Few scenes between the leads are too cute (I found them to be).The love story between the hero and heroine isn't the routine one, it is something new.
At the end I would definitely suggest you to watch the movie. Go with no expectations, sit patiently, after coming out of the theater some part of the movie will be surely struck to you.
