Okay, so this is good business. You take a movie that's already done well, hire a popular actor, someone with halfway decent principles (which in this world means an actor who refuses to dance on Dard e Disco or Ishq Kameena type item numbers), for a halfway decent script (which in this world means sweeping away a script of a critically acclaimed movie and giving it the desi touch) and lo and behold. You've got a brand new standard of what people like. Movie based on another movie that wasn't popular enough to the general masses.
Ghajini, ladies and gentlemen, and Memento. May God give peace to the soul of Christopher Nolan and more sense to Aamir Khan. Not surprised at the swipe, though would've expected something better from the Khan.
