SERIES PREMIERE: Just a notation: Megyn Kellywhen leaving Fox News for NBC, positioned herself in a couple of high-profile places on her new network. One was Dateline NBC, where she entered with an attention-getting entrance by interviewing Vladimir Putin and others, then falling out of the spotlight. The other, long in the works, is her new show and showcase, which premieres today, on Today, as the show’s third hour, now retitled Megan Kelly Today. The first two hours of the show remain the Today show of old, and the fourth hour remains “the days of wine and neuroses” as presided over by Kathie Lee Gifford and Hoda Kotb. Consider Megan Kelly Today a transition pivot between those two very different types of program – which gives her a lot of freedom to set her own tone, whatever that might be.

SEASON PREMIERE: This is the Season 11 premiere of this incredibly successful CBS sitcom, easily the most visible and popular program continuing the multi-camera, filmed-before-an-audience format instituted so long ago by another CBS sitcom, I Love Lucy. Tonight’s program picks up where last season’s comedy cliffhanger ended: with Jim Parson’s Sheldon on one knee, proposing to Amy (Mayim Bialik).

SEASON PREMIERE: This is Cycle 13 of this good-hearted reality competition show – and good-hearted is what makes it stand out from so many others, which is why it just won another Emmy as Outstanding Reality Competition Series. The earliest episodes of each cycle are among the best, because they’re full of discovery and surprise. This cycle, the four judges who will listen to the voices of the contestants, and judge them sight unseen, are always-there anchors Blake Shelton and Adam Levine, recent Voice returning judge Miley Cyrus, and brand new judge Jennifer Hudson, who used to be one of the judgees – as a memorable contestant on American Idol.

SERIES PREMIERE: Because today is the official start of the 2017-18 TV season, CBS is following its season premiere of The Big Bang Theory with that show’s new prequel series, Young Sheldon. Jim Parsons, who plays Sheldon on Big Bang, is here as well – in voice, at least, providing his adult perspective of his own childhood, as this new series revisits his past. It’s a filmed show, as was The Wonder Years, and has a tone commendably similar to that superb period sitcom. It also makes some very smart moves from the start. Iain Armitage, who played the young boy at the center of some behavioral controversy in HBO’s Big Little Lies, is perfectly cast in the title role. Sheldon’s mother, played hilariously by Laurie Metcalf on Big Bang, is portrayed spot-on here as well – and with a genetic advantage, since she’s played by Zoe Perry, who is Metcalf’s real-life daughter. And finally, the writers and producers of Young Sheldon are mining the large backlog of childhood stories referred to during the decade of Big Bang stories. For example: When young Sheldon watches TV, he watches Professor Proton – the TV science host played by Bob Newhart, who originated the role on Big Bang. Terrific touch. For a full review, see David Hinckley's All Along the Watchtower.

SEASON PREMIERE: For the Season 2 premiere, this otherwise negligibly mentionable sitcom makes a major, noteworthy change. Leah Remini, who co-starred as Kevin James’ wife on King of Queens, joins Kevin Can Wait as his co-star on this show as well. Not as his wife – but as his former police partner, a role she introduced at the end of last season. Given this change, the character played by James on Kevin Can Wait wouldn’t have to lose his current TV wife, played by Erinn Hayes– but he will.

SERIES PREMIERE: Jordan Klepper, the snappiest Daily Show correspondent to make the transition from Jon Stewart to Trevor Noah, gets his own show beginning tonight. Comedy Central executives weren’t happy enough with The Nightly Show with Larry Wilmore (though I was), so here comes this new try at holding on to the Daily Show audience in the 11:30 ET time slot – a task that Stephen Colbert found so easy not so many years ago.
