This is the calm before the new-season storm. A week from now, only the most advanced devices will be able to handle the crush of new (and mostly returning-hit) programming airing on Thursdays, with expanded season openers of long-running faves The Big Bang Theory, Parks and Recreation and Grey's Anatomy among the draws.
By comparison, this is a much quieter Thursday, although NBC once had high hopes that the two-hour climax of the seemingly endless and haplessly muddled Million Second Quiz (8/7c) would be something to shout, instead of yawn, about. Instead, the peacock's more anticipated headliner is Valerie's Story — A Meredith Vieira Special (10/9c), an hour-long good-news report from the former Today co-anchor chronicling Valerie Harper's unusually public battle against terminal brain cancer. Fans turned out in big numbers earlier this week to see Harper, a still robust 74, in radiant and jubilant form as she took a twirl on the Dancing With the Stars stage — "Way past my expiration date, and I'm dancing!" she crowed — earning three 7's and a standing O for her fox trot. The news special will look back at her treatments and never-give-up attitude that has been a hallmark of her struggle since being diagnosed earlier this year.
