3 Good

The Ghajini is all dependent on Aamir Khans acting like Heath Ledger was hero being a villain in "DARK KNIGHT", Aamir has to do something amazing as that to get ghajini its due.
As most people dont know that reason MOMENTO became famous and caught eyes was because the kind of portrayal it does of amnesia is scientifically and psychologically proven to be closest to real in modern day. So, Aamir has to keep that essence and i am afraid either director or aamir will lean it more towards action , which can ruin the movie.
Else i've got my fingers crossed!!!
