I never liked "koi mil gaya". There was something about the movie which did not click with me, but with krrish, I think it clicked.
The movie is about the son of the character of koi mil gaya hero - rohit, his love priyanka and his old dadi - the famous rekha.
It starts off with a few boring scenes and dialogues bringing the story in sequel with the earlier "koi mil gaya". The part before the interval keeps on revolving around our "hero in the village" and his love story with our heroine. During which there is some good comedy.
The actual movie starts after the interval when our hero goes off to singapore to get our heroine back to his village.
Climax has a twist which I wont reveal over here. But the entire movie is worth the climax. There are some fight sequences in the climax which would remind you of "phantom comics".
Songs pop out just like that and are not that good...
On the whole the movie is worth atleast one watch...
