Before watching Ghajini, i have heard so much about the movie and its resemblance with Memento. I didn't have the chance to watch Ghajini Tamil version but i did watched the original Memento long ago and was thrilled to see such a complex and gripping thriller. Anybody who has watched Memento would hardly like Ghajini, The concept is same (Hero suffers from STML and more disappointing was to see Amir using same techniques to remember such as using Polaroid photos and Tattoos on his body). Rest of the story was different but then its an Indian movie, prolonged unnecessarily for 3 hours. If anybody disagrees with me, they should see Memento. It short this movie doesn't even have a single thrilling or suspenseful moment, rite from where Ghajini was shown in the movie it is clear he is the killer of Amir's Girl.
