it's not true that indian movies are all about remaking, there are many original works which are just awesome movies. But the fact is, remake movies are more famous/popular, got the brightest stars, very expensive and highly advertized, so that people generally know the indian film industry by those remade-Thingy.
Talk abt the 'Munna bhai' movie, which is being remade in hollywood. Satyajeet Roy own an oscar for God's sake. There are plenty of creative personalities like Mira Nair. But the fact is, most producers and storywriters in the indian movies are not very interested to go through the back-breaking pain of creating something brand new. We'd need more talented people in the script writing/directing/concepts depertments
