Speaking to The Guardian, the Men Behaving Badly star revealed that she was not impressed with her recent TV roles.
When asked whether she had any career regrets, Quentin replied: "Oh God, most of it.
"I hear radio plays that I did 20 years ago and I can't bear it; I see things on telly that I made six months ago and I just hate them.
"I could name on one hand the things that I think are okay; the rest of it is just rubbish and embarrassing."
Quentin filmed the last series of BBC sitcom Life of Riley last year, and currently hosts ITV1's Cornwall.
