Great indian directors

I am not really a big film buff,but there are some filmakers i realy admire especially someone like hrikesh mukerjee,mani ratnam,and in recent times nagesh kukunoor.The works of a great director is visible at the very first onset when the visuals,the way a particular scence is being coordinated and narration of story is done,for instance if you take mani ratnam especially if you see his earlier works in tamil the prime importance is given to the script rather than other aspects,even a certain silence in a particular scence has the power to express a lot!!Ofcourse every director has his or her own way or genre of work.If you take for instance hrikesh mukerjee his way of filmmaking primarily focussed on the simple instances in life which we all miss out and human emotions and mostly tapped the natural character of human being.If you take someone like karan johar which some may not include in great directors but his films of genre entertainers do have some niche audiences who are very much happy with the film he makes and may be called as "paisa vasool" films.Even the very likes of david dhawan and priyadarshan who basically create comedies which may be seem sometimes senseless ones but are able to make people laugh and reliev them of stress.Or the more creative director like sanjay leela bansali who creativity and sets are more of focus than the film itself.but his khamoshi was hugely appreciated even tough not accepted by audiences.All and all every film maker is born with certain special talent which he tries to convey thru his work and some are expertise in that and win accodales but what makes the director special is when his/her film becomes a superduper hit,then he is automatically termed a great director from both critics and audiences side!!
