என்றென்றும் புன்னகை-ஜீவா த்ரிஷா சந்தானம&

Yes, the gags were taken from several places. Liked the Santhanam's Chaplin drunken act. He did it with ease.
By the way, its good to hear a french song in the Swiss pub which is indeed the correct ambiance and suits the situation if you know the song. The song is : Comme toi (Like you)
Other than that Trisha is worth watching. I always liked here elegant walk.

A fun filled movie that is super in the first half. Ignore Jiva and enjoy the movie. Santhanam is hillarourious. Vinay has pulled of a good role. Looks to have put on weight. Trisha is gorgeous, specially in sarees.
All the overseas scenes can be skipped and you wont have missed much.
Worth watching for the comedy and Trisha and the bonding of the three buddies. For me, this movie works.
