A spinoff of any sitcom is always risky, especially when there is a high standard to live up to. Frasier broke the mold by being as well received as its predecessor, Cheers. The titular bar was a place for a group of friends to meet and discuss their daily lives, bringing well-known stars such as Woody Harrelson and Rhea Perlman on the scene. As one of the bar-goers, Frasier (Kelsey Grammer) brought a dry wit, which transferred well to his own show.
