The talk this week has been about the "American Idol" judges and not the "American Idol" finalists.

And that helps explain what went wrong with one of TV's biggest hits. The squabbling diva judges upstaged the hard-working contestants. There's more chatter about Nicki Minaj and Mariah Carey than the two gifted women competing for the title.

But Candice Glover and Kree Harrison will perform in the one-hour show at 8 p.m. Wednesday on Fox. Candice may have had the smoother run on "Idol," but Kree could have the staunch support of country fans. Carly Rae Jepsen also sings "Take a Picture." The season winner will be named Thursday.

The other highlights Wednesday:

"CSI" rolls to its 13th season finale at 10 on CBS, and producers plan an event. Black Sabbath performs, and the guest stars include Eric Roberts, Tim Matheson and Annabella Sciorra.

"Arrow" completes its successful first season for The CW at 8. The Dark Archer (John Barrowman) is causing more trouble, which will mean good things for the drama. Then "Supernatural" delivers its season finale at 9 on The CW. Both series will return next fall for the struggling network, which is good news for fans.

The entire ABC lineup is new. But "Family Tools" at 8:30 and "How to Live With Your Parents" at 9:30 won't be returning next season. The well-acted "Nashville," at 10, will be back with more songs and heartache.

But you'll have to wait till next Wednesday, the final night of the 2012-13 season, for the ABC season finales. The brightest spots on ABC's Wednesday lineup remain "The Middle" at 8 and "Modern Family" at 9. Jack McBrayer ("30 Rock") plays a dental patient on "The Middle," and Phil gets an RV on "Modern Family."

In drama, there are new episodes of "Criminal Minds" at 9 on CBS, "Law & Order: SVU" at 9 on NBC and "Chicago Fire" at 10 on NBC. "Chicago Fire" features Jason Beghe, who will star in a spinoff of the freshman drama next season. "Criminal Minds" offers its two-hour season finale next week.

If that's all too dark for you, USA delivers a fresh episode of "Psych" at 10. It will be sandwiched between repeats of "NCIS," which concluded its 10th season Tuesday night on CBS. The "NCIS" finale was pretty dark, too.
