Mumbai: Actor Jimmy Shergill says he is very critical of his work and even though some of his films are highly appreciated he still feels that he could have done them better. Jimmy, who is busy promoting the forthcoming film "Madaari", told IANS: "I am my biggest critic. I am very critical about my work. I do films which get highly appreciated by everyone, but I still feel I could have done it better. "I have that issue... That's the reason I don't watch my films. No matter how big a film it might be, I don't watch my films...." However, Jimmy is thankful to the critics and audiences who have appreciated his work. "I think I am very lucky that people have never criticised my characters. They might have criticised the film, but not my character. I am thankful to the critics and audience for praising my work," the 45-year-old said. Miraj Entertainment and Bharat Shah, in association with EaseMyTrip.com, are presenting "Madaari", a Paramhans Creations production. The film is directed by Nishikant Kamat and is all set to release on July 15.
