An often copied, rarely duplicated classic about TV writer Rob Petrie at home and work is as close as it gets to sitcom perfection. Sharply written, warmly acted by a brilliant ensemble cast and often sublimely funny, this brainchild of sitcom veteran Carl Reiner (who honed his comic skills working nine years with Sid Caesar) won many Emmys and, though it ran for only five seasons, has remained one of the medium's most enduring series.
