I loved Sathiya.  I liked Bunty & Bubbly, but Jhoom Barabar Jhoom sucks big time. After the first half I asked myself "what happened till now" and the shortest answer that came to my mind was "nothing".  

The story goes like this. Abhishek and Preety meet at railway station and spend couple of hours telling each other about their fiances. This part takes the first full half of the film. In the second half we are told that all the story that were shown in the first half were fictitious and these guys are in love. So one of them calls up the another and they go to a dance compition with their "cooked up fiances". After the dance competition that lasts about 20 minutes, the cooked up fiances start fancing each other and elope. And our couple also finds out that their perspective other half is not engaged and .... the end. 

This is one head aching film. Avoid even if you get free tickets.
