When this show first premiered, it was thought of only as a jiggle show. However, it turned out to be one of the best examples of slapstick comedy in the history of television. John Ritter showed that he was a master of physical comedy and it really showed on this show. Another thing that really helped to make this show great was the whole ensemble. I feel that Joyce DeWitt was totally underrated in her role as the sensible Janet and that she was the perfect counterpoint to Jack's leering personality. The only thing I was disappointed with was how they devolved Suzanne Somer's character, Chrissy. If you look closely at many of the early episodes, Chrissy wasn't quite the dumb blond that she later turned out to be. If anything she was more naive then dumb. Other than that, this show will always be a classic of the era it was produced in.
