Read until the end to understand how genius this movie is (spoiler Alert)...i Agree when people say the movie's ending is kinda disappointing.. i felt the same until i realized the magic Elan did in the movie...
I realized that after 3 hours cause i was thinking he did a good job with the movie why screw the ending... then i made the connection... remember the first scene of the movie where young kalai gets ready for fancy dress competition and the Barathiyar Meesai got lost ..the father said... through your acting you must make the audience forget about the mustache... that when you accomplish as a performer ...
and the same dialogue came is frozen scene shot at the hospital scene ending when director says cut... the entire hospital scene kalai(kavin) doesn't have scar on his face... the entire hospital scene is a movie shoot. the director made us forget his scar and focus on his acting ... untill the part he receives a call at vetri maran office was reality but somehow everything turned out well...
the director created a magic by proving his dialogue in the hospital scene.... through your acting you must make the audience forget about the scar... that when you accomplish as a performer and emerge as a star... bravo entire team... in this movie kavin is not the only star... entire crew is ...well done
