Time marches on

"Once Upon a Time," the fairy-tale series for grown-ups, celebrates its 100th episode with an attempt to rescue Hook. Lots of familiar faces will return for the rescue mission and because this is fantasyland, don't rule out appearances from the dead. Minnesota native Eddie Kitsis continues in his role as executive producer.

Baptism by fire

A Baptist church in Georgia is the setting for "Saints & Sinners," a new mystery series about how a murder rocks the very foundation of the congregation. Sounds compelling, although I'd be even more intrigued if it was the same church that hosted the castaways from "Lost."

Single and ready to mingle

Caitlyn Jenner may insist she's not on a never-ending publicity tour, but the reality star is all too happy to share her new life in a second season of "I Am Cait," which will give us a peek into her dating life. Turns out being on cable TV is a more effective app than Tinder.
