The Big Bang Theory. What better way to kick off the broadcast networks' traditional premiere week than with the 12th (and final) season opener of TV's most-watched show? It'll be back again at 8 p.m. Thursday as it moves to its regular time slot. 8 p.m. Monday, Sept. 24, CBS.

Jane Fonda in Five Acts. Frank and thoughtful documentary from Susan Lacy, who created and for many years produced American Masters for PBS, takes the actress and activist through the stages of her life, including those that were too often shaped by the men she was with. 8 p.m. Monday, Sept. 24, HBO.

This Is Us. Randall (Sterling K. Brown), Kate (Chrissy Metz), and Kevin (Justin Hartley) celebrate their 38th birthday in the third-season premiere. I'm sure it'll just be cake and ice cream and good times, right? 9 p.m. Tuesday, Sept. 25, NBC.

The Good Place. I cannot say enough good things about the hourlong season premiere of one of the most inventive comedies in years, starring Kristen Bell and Ted Danson. I should not,  in fact, say much at all, because I wouldn't want to spoil a single moment of it for you. But it's called "Everything Is Bonzer," and Mike O'Malley is in it. What more do you need to know? 8 p.m. Thursday, Sept. 27, NBC.

Murphy Brown. Twenty years after a series finale in which Murphy (Candice Bergen) interviewed God, most of the gang from FYI — including producer Miles Silverberg, played by Wayne's Grant Shaud — is reunited for a new cable news show, Murphy in the Morning. I haven't seen the premiere, but I wouldn't be terribly surprised if it were to be somewhat political. 9:30 p.m. Thursday, Sept. 27, CBS.

The Cool Kids. As Tim Allen's ABC-canceled Last Man Standing gets an 8 p.m. Friday revival on a new network — with a number of winks involving its cancellation and the recasting of two characters — Fox pairs it with a new show, created by It's Always Sunny in Philadelphia's Charlie Day. Vicki Lawrence, Martin Mull, David Alan Grier, and Leslie Jordan star as four rebellious members of a retirement community. 8:30 p.m. Friday, Sept. 28, Fox.
