There was a time, when some South Indian movie lovers, who were ardent fans of Bollywood films, used to comment on South Indian films, especially the Telugu and Tamil films about the quality of film making here.The main point they used to say was the originality of stories there and how some South Indian film makers used to remake or freemake them.
But the times have changed and so have the type of films being made there in Bollywood. If you look at the films coming in the recent past in Bollywood, majority of them are remakes of South Indian films, especially Telugu and Tamil films. If you watch those remakes, you will certainly get a feeling that the original south Indian films are far better than those remade versions.
It doesn't mean that all Bollywood films coming are remakes. Still some original masterpieces are being made in Bollywood. But now there is no chance for Bollywood movie fans to comment on South Indian films.
