Personally, I liked all of them. But I will rank them:

1. Jab Tak Hai Jaan – Yes! There was more serious acting in the movie and I think he carried it off well.

1. Chennai Express – Well, he did play his age – And i kind of liked the ending. It was a good movie, with the same kind of boy-meets-girl plotline we usually see in hindi movies but trying to keep things comedic and light. The comedy didn’t always come out, but it was a good no-brainer movie.
2. Happy New Year – Even though i liked this movie a little better than Chennai Express because the entire cast was amazing, it is certain elements that made me put it under Chennai express. Firstly, the fire-catching-chemistry – UGH!, secondly “Mohini” is an amazing dancer until she tried to teach the men and until all the dances till the finale, and then amazingly they ALL dance well in the finale! What?! 2 the opening scenes, most of the characters opening scenes were cringeworthy! And a few other smaller elements here and there. But gain, a good no-brainer watch!
