I never would have watched this movie, had it not been for the hype and hoopla surrounding it... and I have learnt a lesson - never watch a Simbu movie, how much ever it is hyped! First half was watchable, but the movie goes totally haywire in second half. It is obvious that Simbu was all at sea. None of the characters seem to be well etched out.
Simbu has tried way too much and failed miserably. The worst thing about the movie was Simbu trying to be superstar - the close-ups (which are scary), punch dialogues, his so-called style and actions. Does he really think people like watching him do all that? And, poor poor Reema Sen - she has never looked so bad till now, and i don't think she will look worse than this!
Yuvan's music was hyped as well. But, nothing great there. Vallavaa was the only song which was listenable. I still don't understand why people go ga-ga over Loosu Penne. That is one of the most irritating songs I have heard. Re-recording was noisy at some places, making the dialogues inaudible.
Vallavan is way too much toruture (more than 3 hours) to inflict on oneself, however much one is angry with oneself! Please avoid!!
