Boomers get another show

No one will ever confuse the Baby Boomers with the Greatest Generation. On the flip side, no one has written a book just yet called Gen X: How the Boomers Took Your Job, Stole Your Pension, Wrecked the Economy and Ruined the Planet. As the timely but not entirely groundbreaking program The Boomer Revolution shows, boomers enjoy talking about themselves, and they’re about to do a lot more talking. Broadly defined, boomers include anyone and everyone aged 48 to 67. The Boomer Revolution warrants an entire series, but for now a single program will have to do. Thursday-night TV has to make room for boomer shows like Grey’s Anatomy, The Office and Elementary, after all. (9 p.m., CBC)

The Office may have been made by boomers for boomers, but it is about to retire — in May, to be exact. Thursday’s first of two episodes is a repeat from last month, in which Pam (Jenna Fischer) inadvertently brings lice into the office, prompting a lice infestation and causing Dwight (Rainn Wilson) to embrace his inner exterminator. (9 p.m., NBC, Global)

Community is just as frenetic but not as funny in its new season without creator and head writer Dan Harmon — proving, once again, that while we watch TV for the characters, it’s the writers who provide those characters’ voices. Malcolm McDowell appears in Thursday’s episode as Noel Cornwallis, professor of European history, with all that that implies, in an outing called Alternative History of the German Invasion. (8 p.m., NBC, Citytv)

Once again, the boomers are judging the newbies. Randy Jackson, age 56 and a boomer if ever there was one, returns to the judges’ table in American Idol, as the final group of 20 semifinalists take the stage and “sing for their lives,” in Idol’s overheated argot. Ten will stay, 10 will be cut, and by the end of the evening this year’s competition will be down to the Top 20. (8 p.m., Fox, CTV Two)
