Shabana Azmi was a terrible terrible actress. She was a star kid being Kaifi Azmi's daughter and her mother was also an actress...So she got many mainstream roles in the beginning. But she was a total flop..people did not want to see her and her depressing screen presence and pathetic acting.
So then she started doing what was called parallel cinema. And the times were such that few people watched those movies but automatically one would get counted in the intellectuals and good natural actors category which was totally an untrue thing but that was the perception created those days and it continues to this day.
Smita Patil was one great actress. She did parallel cinema because of her love for that medium. She found so much success even with her parallel cinema movies and then once for some reason she was snubbed for a movie called Party and she was so sad that how the so-called intellectuals group who she thought were her ftiends had ditched her. So then she did some mainstream movies and she was a huge success there also.
So yes, her because she's a kalank on the name of acting.
And another one like many mentioned here is phata dhol Farhan Akhtar.
