i watched ghajini & memento both..i found memento a bit boring, slow & confusing at times(since the story ran backwards), but ghajini was entertaining,if you do not look at it logically ,the core story is similar to memento but the story of amir & asin is what makes this movie entertaining..& also the fight scenes were cool although baseless..like the last fight..where amir hits the 1st guy while chasing ghajini...the guys head rotates 180 deg.WTF?? anyway the movie is purely meant for entertainment so i was not thinking much.i give it 3.5/5.
