Jennifer Hudson, who never quite won “American Idol,” but did get an Oscar and Grammy later, joins the judges’ panel on the 13th iteration of “The Voice” (NBC, 8 p.m.), the singing competition that inexplicably won an Emmy for best reality competition last week. Hudson will join Miley Cyrus, Blake Shelton and Adam Levine in the spin-around chairs as blind auditions commence.
In addition to being an incubator for all new comedies that follow it “The Big Bang Theory” (CBS, 8 p.m.) remains, in its 11th season, the most popular comedy on TV. They lure people to the premiere tonight to see if Mayim Bialik’s Amy will accept the wedding proposal of Jim Parsons’ Sheldon.
If the debut last year of “Kevin Can Wait” (CBS, 9 p.m.) seemed like a thinly-disguised reincarnation of Kevin James’ previous “King of Queens,” you won’t believe what happens this year for season two, when they actually kill off the character that had played the wife in the domestic comedy, Erinn Hayes, and bring in Leah Remini as the love interest. Jerry Stiller is waiting at the door.
Also returning tonight is “Scorpion” (CBS, 10 p.m.) for its fourth season. By now it’s become a kind of nerdy save the world drama with humor. Tonight, the team is being forced to work with old nemesis Mark Collins.
