Query: A very intense thriller

"Ghajini" is a very intense thriller. The hero's fiancée is killed by mobsters. The hero suffers brain damage from the attack and can only remember the last fifteen minutes. He constantly makes notes to himself as he tracks down the mobster. The hero is played by Aamir Khan who starred as the kind nice teacher in "Taare Zameen Par," which also he directed. The movie is well done, but violent. Not your typically Bollywood movie.
