About copying movies actually there's no point in blaming the movie makers. The indian cinema audience is simply retarded. Original scripts and good cinema is hardly appreciated now-a-days, movies which suffered from this fate are Black, Lakshya, Swades, Yuva(minus the songs), and there could be so many other examples where movies which were very much sensible, superb direction and an original script but din't do well at the BO. Thats the part where indian film audience sucks..............
Whereas wholly lifted movies from directors like the bhatts, sanjay gupta etc (who just rent movies and life everything) are recieved very well by the audiences. Please stop sending the wrong vibes to the film makers. Unless people stop watching such movies those filmmakers are going to try and play safe and stick to copying movies from other sources since those have already been time-tested.
