The movie is all about a cat - mouse game between Dhanush and Prakashraj and its a racy entertainer with a lively screenplay. The movie never sags at any point and they have pulled it off with lot of comedy w/o any violence or vulgarity.
Its a tailor made movie for Dhanush and he does a neat job. Take this as a sample.
Policeman: உன் பேர் என்ன டா?
Dhanush: Police தானே... கண்டு புடி...
Shreya just comes, dances, cries and goes. Prakashraj has done his part very well especially when Dhanush takes him for a ride.
The Karunas-Dhanush combination has worked again with some sublime timing from Karunas. The tasmac shop scene is one.
Mayilsamy : Glad to meet you
Karunas (intoxicated) : என்னது கெழவிய காணுமா?
You must watch the scene... :-)
One other character who I liked very much was the kid who plays Dhanush's brother. He really does give Dhanush a ride in the scenes they are together. Mouli and Charanya do a neat job as the hero's parents.
Special mention has to be made about the dialogues. They are just stunning in many scenes. Another sample here.
Dhanush to Prakashraj : "கேக்கரவன் கேனப் பயலா இருந்தா K.B. சுந்தராம்பாள் R.B.செளத்ரி படத்துல நடிக்குதுனு சொல்லுவியே..."
Prakashraj's aide to Prakashraj : "அவன் பொங்கலுக்கே வெடி வெடிப்பான், இப்போ தீபாவளினா சும்மாவா இருப்பான்?"
One scene that's a bit too much is where Dhanush comes out of an SUV with bluetooth in his ear in a politician's get up - இது ரெம்ப ஒவர்!
Amidst the crap movies currently doing the rounds, this one is really a whiff of fresh air. Go and watch it! Its worth it.
