Sunny Deol is his own biggest critic

Actor Sunny Deol says he is the biggest critic of his work and knows it very well when his performance is not upto the mark.

The 57-year-old has been a part of movies like "Darr", "Gadar - Ek Prem Katha" and "Yamla Pagla Deewana".

"I am my biggest critic. I know best where I am right and wrong. At times you will not see me happy when people say, 'Wow, what a shot'. I feel, 'What was this, I didn't deliver what I want to'," said Sunny, whose latest movie "Singh Saab The Great" released Friday.
