His first film 'Socha Na Tha' was a movie about a guy 'X' in love with a girl 'Y' but his parents want him to marry some other girl 'Z' and finally he falls in love with the girl his parents choose for him - 'Z' and the story ends.
His second film 'Jab we met' was on similar lines where a girl 'X' is in love with a guy 'Y' and on her journey to convience him she falls in love with some other guy 'Z'... and story ends
Both were light hearted movies.
In 'Love Aaj Kal' boy 'X' and girl 'Y' both are in love with each other but they realize it on the day the girl marries someone else - 'Z'!
And then Y dumps Z and gets back to X. Some crazy stuff... I found it very immature.
I wonder what Imtiaz's next film story is... X and Y in love with each other and X gets married to Z has kids and all and 10 years down the line realizes he actually loves Y!
Love aaj kal is a pathetic movie with stupid story and an actress who doesn't know how to act...
