Mumbai: 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.
