engrossing film

I watched Memento recently, after knowing that the upcoming movie Ghajini is loosely based on it.

The way the story is presented in parts and in rewinds is quite innovative. Each time we have to change lot of our assumptions entirely, and so it changes our perceptions about the characters. Its like a big puzzle and you are being given small hints sporadically. You get totally engrossed.

It will be quite interesting to see how Ghajini is made (or changed?) to suit Indian audience.
