most of you are quite right.
With Ramcharan the only problem was he chose the wrong film to make his debut. Should i say Dhanush intilligent or smart, becos he literally knows how bollywood works, and he choe a role which he knew that he can fit well. but still the charisma he was as kundan still holds a lot more praise. moreover i also feel he doesnt see any career or plan anything in bollywood, its just he thought to give a try and thankfully he succeeded, becos he indeed has a pretty good lineup of tamil films, and also did very good with Maryan.
and yes, many people were more curious becos he was the kolaveri star, and again he deserved that becos, i still dont know any indian, leave tamil, any indian actor/singer to generate that much craze with a single song which he did worldwide.
tthen a time came, when i was just fedup due to the kolaveri craze here, and now after watching Raanjhana, i started listening the song again only to connect Dhanush in both the places.
He will prove to be iconic, becos very few actors have the quality to make people forget everything and just focus on a single person blindly onscreen, for once in Raanjhana or Maryan i dint bother how he looked, he made everything so mesmerizing and beautiful.
Zanjir with the bad reviews and also the flop status, i have let go off the plan to watch it.
