Disappointed. Karthik , you can do better...little madurai(not TN or India..very unlike 'Little China'..)and what was all the grotesque ,swanky imitate style of Rajani, really ??..
Look at the story, do you see an overdose of (much avoidable)superfluous sentiments,singular rubble, unimaginable superhero portrayls...imagine a killer who goes around slitting throats, and he wakes up after a 'supposedly moving story of immigrant's '...sic.
As for Dhanush, a brilliant actor, but just be yourself..there are so many character roles where the hero need not be a MACHO!..even a candy man or elevator boy or cab driver, why even a concierge can be a hero and you can do a stellar job..flashing machete, sub machine guns two in hand and one over(.i hope you know how much those BIG toys weigh) shoulder? Really....?!!!...
Bottom line poor attempt and a confused team...who attempted making a dragonfly lift the dragon!
