The first season aired on ABC in 1994, was cancelled after the end of the season, but picked up by FOX for season 2 in 1995, which saw a rise in viewership, but ultimately ended in cancellation as well (plans for a third season on UPN fell through, though a series of internet shorts were made in 2000).
The Critic was about the life of Jay Sherman(voiced by Jon Lovitz) who lived in New York City. He was a fat, bald movie critic who never gives a positive review. He has basically no friends and everyone hates him. Each episode had a parody of a movie Jay was reviewing that were usually 2 or 3 years old. It was probably FOX's biggest mistake cancelling it. Now they broadcast dogshit like American Idol and reruns of Becker. It only had 2 seasons.
