CBS has yet to answer the “what to do about Saturday” question, programming a special and movie in place of its sophomore half-hour series “Brooklyn Bridge,” which was yanked after Saturday’s broadcast.Getting poetic The network will air “Dead Poets Society” from 8-11 p.m. this Saturday and the half-hour special “Miracles” in the “Bridge” slot Nov. 28, but no additional scheduling has been set. “Bridge” was the last surviving component of the web’s initial Saturday lineup, though another show, the Columbia Pictures TV series “Raven,” remains in production and will return later this season, while “Frannie’s Turn” and “Angel Street” were canceled. Six segments of “Brooklyn Bridge” have aired thus far, averaging a not-so-kosher 6.2 rating, 12 share in Nielsen. The show is officially on hiatus and will complete production on 13 episodes with the remainder possibly to air in the spring. (Paramount came into the season with a 13-episode commitment that gave CBS the option on nine additional segments.) Critical fave The expensive half-hour, which received an Emmy nomination as outstanding comedy series in its first year, was a critical favorite but never caught on ratings-wise. The Gary David Goldberg-produced show was the only new series CBS introduced last fall to be picked up for a second year, largely on the strength of that critical cachet.
