Story: Exact duplicate of 3 idiots. No changes in story. Story with messages about aspiring what you want to achieve and choose a profession upon interest. Good message, Comedy, romance, drama and friendship element story.
Casting: Vijay played the role of Panchavan Parivendhan( Ranchodass chanchad). Ya of course it is a known fact that this would be his different approach and better than any other character he did commercially. But still he couldnt bring up the Ranchodass character as good as Aamir Khan. There were part where his dialogues were not so convincing to show Rancho wisdom or potray a humble Genius student. But the second half was his play, he did well from the scene Jeeva got admitted in Hospital till the end. Especially climax he manage to get it perfectly. And we have Jeeva playing Sevarkodi Senthil (Raju Rastogi). Jeeva was the Man of the match i would say. I can say he is another Raju Rastogi with better Humour. He really showed he is the best man for that role. Srikanth played Venkat(Farhan Queshi a.k.a Madhavan's character) who wants to be a wild life photographer. He was equally good. The lead lady Ileana played Ria (Pia in Hindi), Parivendhan's love interest. She is one sweet girl who has good gestures that can replace Kareena. She was like an angel. Maybe her lip sync was not that convincing but she did a good performance as well. Of course what is 3 Idiots without Virus played by Sathyaraj. That was one awesome performance by Sathyaraj as well. And not forgetting Silencer played by Sathyan. Sathyan brought the Silencer character very well except there were some part where he was quite artificial. Supporting role done by S.J.Suryah, Anuya (SMS fame) and many others.
Screenplay: There is nothing much to say about the screenplay since most of the sequence were from adaptation of 3 Idiots. Except there were additions in comedy dialogue which is really good. The cinematography was good. Maybe this is because this is the first time Shankar working with Manoj Paramahamsa. It was different and lively with a different shades with less concentration on HD. Unlike usual Shankar trend, the songs were not in grand affair. They used the same ideas used in Sivaji and Anniyan. 98% of the scenes were same with 3 idiots including dialogues. Yet the screenplay was in slower pace than 3 idiots made it look lengthier. Good Intro with yen friend's pole yaaru macha.
Music: The music was composed by Harris Jayaraj. Superb song after so long. It really added value to the movie.
Plus Point: Story,Screenplay, Music,Comedy,Moral Values and casts.
Minus Point: Lengthy and no originality.
Verdict: Full entertainment package. Can be watched many times in cinema. Commercially made.
