“Knight Rider”: 43 minutes of bad road

KnightriderRough debuts last night for NBC’s “Knight Rider” and CBS’ 8-9 p.m. comedy block of “The New Adventures of Old Christine” and Jay Mohr frosh “Gary Unmarried.”

ABC’s “Dancing With the Stars” stomped all over everything in the opening hour of primetime, drawing 15.6 million viewers and 3.5 rating/10 share in adults 18-49.

Peacock’s remake of the ’80s talking-car skein brought in 7.3 million viewers and 2.4 rating/7 share in adults 18-49. “Old Christine” (6.7 mil, 2.1/6) and “Gary Unmarried” (6.8 mil, 2.3/6) came in even lower.

President Bush didn’t help things with his dour 15-minute address at 9 p.m. EST, pushing back the start times of the rest of the night. CBS’ fortunes picked up with solid showings from the season openers of “Criminal Minds” and “CSI: NY” (reliable numbers for those shows won’t be available until later today because of the delay).

Overall, CBS won the night in viewers and 18-49 by a solid margin, with ABC running second, even though the Alphabet didn’t do much business with its two-hour David Blaine spesh.
