Just a brief look at his Hindi movies alone,
Ram Gopal Varma
He debuted into Bollywood with Shiva (1989), the Hindi remake of his own Telugu hit Siva.
This was followed by several movies which introduced the audience to the creativity infact RGV's kind of films. The films included Drohi with Nagarjuna again & then Raat with Revathi, a terrific horror film. Both the films were bilingual & both were not successes.
Then, RGV came up with one of his best film, Rangeela. Though not a big success it helped create the brand, called RGV. But he followed it up with a flop, Daud. Though not a bad film, people were simply weren't ready for this.
The man is not known to back away. The failure of Daud didn't shake him at all. He went back to his roots, came up with the film that went deeper inside the gangster world. With Satya, his Shiva seemed to be just a showreel. Again, he was kept waiting for the box office success but RGV had successfully established himself as one of the best directors in India.
He then went back to his experimentation mode, not caring for the box office success. This is what gave us Kaun, Mast & Jungle. With his lady luck, Urmila starring in all the three films there was no looking back for him. Whatever the box office verdicts might be, the one thing which was common for these films were the critical acclaim. Plus the commendable thing was, all these varied genres films released in a span of 2 years, 1999 & 2000.
With Jungle, he tried to repeat his luck he had in the Telugu blockbuster Kshana Kshanam (his all time best) & forget the failure of Daud. After this he went back to his usual gangster drama to give one more superb film, Company. After Company, he wanted to romance the horror genre again, a genre which he adores. He gave Bhoot, one of the most memorable films in the horror genre.
Downfall of RGV -
Post Bhoot, his lady luck was replaced. Sure he gave few good films here too but the majority ones were just the product of his arrogance. His arrogance to prove he is right & his arrogance to prove that he's always right. With this came the movie which was made to only showcase Antara Mali as the next Urmila.
This was followed by a really well made film, Sarkar. His association with Big B, probably made him give another good film, Nishabd. After that, notable films were, Darling, Rann & Rakht Charitra-1. Even his Agyaat was not that bad.
But now, it's not these movies which RGV is remembered for, it's the wrong movies which he's forcefully feeding his audience for the reasons best known to him.
RGV lacks what his counterparts, The Bhatt brothers have.
