You got to give it for the man and his ideas which are showering collections abroad, while he lives in the shades in the Telugu Industry. If you have no idea what we are talking, watch Hangover and Get the Gringo and you will get one.
You can dispute over its box office collections and run, but you can't have much of a dispute that 1-Nenokkadine was a movie ahead of its times. Same goes over to trend-setting romantic flick "Aarya" (mind you, it was a block buster at the box office). "Sukumar is a director set for the future".
Watch Prasthanam, and if you still have any arguments of him being in this list, do watch Prasthanam again.
Try to narrate the plot of "Manam" and you will get a clear view of the Genius Vikram Kumar is. The screenplay of "Manam" will be preserved for the future generations. Not taking anything from his stunning psychological thriller "13B", this "Ishq" Director has screenplays for the future.
Now here is one guy who dared to think out-of-the-box right from the onset. His films(Gamyam, Vedam, Krishnam Vande Jagadgurum), have a strong message as an undercurrent passing through their veins, while also being technically sound. His next flick is a historical action drama 'Kanche' with Varun Tej. We're definitely excited!
This list is incomplete without the master.
P.S : His movies speak for him.
