Really, bro? Have you actually seen a Bollywood film? And, no, "The Love Guru" doesn't count. The mainstream Hindi film industry has two detective/mystery films out this year - one of which, "Kahaani", was superb by almost any standard. The other, "Talaash", should also be fantastic, if Aamir Khan's track record is anything to go by.
You need to take your condescending attitude back to NYU film school for another semester. And don't talk about things you don't know.
