If I had to list my favourite Hindi films from recent times, they would be Black Friday, Satya, Rang De Basanti, Dev D and a few more. But the name of Anurag Kashyap keeps floating about in most films I have liked. Either as a script writer or director or even as producer.
I am not a fan of Anurag Kashyap the person, as much as I am a fan of films he has been involved with. I do not know about his philosophy or his struggles. I have never really tried to search for such information nor have I easily come across it.
Another actor I am a big fan of is Robert De Niro; again people hardly know much about his private life. But he still manages to have millions of fans. They are not exactly his fans but fans of his work.
These are not people who are celebrated but these are people who choose to have only their work celebrated.
The point here is, this sort of popularity has nothing to do with talent or ability, but to do with choice. In other words, being a private person is choice and not necessarily an achievement or a personality quirk.
