Reality television may no longer have the big surprises you'll find in the NCAA basketball tournament, but some major reality series will try to dazzle viewers this week. A few highlights:

1. "The Voice" returns to NBC at 8 p.m. Monday. Usher and Shakira join Blake Shelton and Adam Levine on the judges' panel. "The Voice" was so crucial to NBC's short-lived comeback in the fall that any changes to the singing contest will be studied closely. NBC averaged just 3.8 million viewers in prime time last week, so the Peacock Network needs a lift from "The Voice." The blind auditions start Monday in the two-hour season premiere and continue in a one-hour edition at 8 p.m. Tuesday.

2. "Dancing With the Stars" began a new season with 17.1 million viewers last week, a 21 percent rise from the fall premiere. But "The Voice" is likely to cut into the dance contest's ratings this week. The couples will perform a jive, quickstep or jazz routine at 8 p.m. Monday. Josh Groban and Icona Pop perform on the first results show at 9 p.m. Tuesday. Unless D.L. Hughley transforms himself into the next Fred Astaire, he is likely to be voted out first.

3. The eight finalists on "American Idol" perform the music of Detroit at 8 p.m. Wednesday. Filling the two hours with song will be Lazaro Arbos, Janelle Arthur, Candice Glover, Kree Harrison, Amber Holcomb, Angie Miller, Burnell Taylor and Devin Velez. The male contestants will have to be especially good to avoid elimination. You may hear extra judges' chatter to fill that time. Colton Dixon from season 11 of "Idol" performs on the results show at 8 p.m. Thursday. That will be the 450th episode of the Fox singing contest. How much longer can "Idol" go?

4. "NCIS" brings on Jamey Sheridan ("Homeland") as the estranged father of Tim McGee (Sean Murray), at 8 p.m. Tuesday on CBS. The dad is an admiral who is a suspect in a murder aboard a U.S. Navy ship. The episode also features guest star Joel Gretsch. "NCIS: Los Angeles," at 9 p.m. Tuesday, wraps up a two-part episode that sets up a possible third "NCIS" series with Kim Raver and John Corbett.

5. The ABC comedies are all new Wednesday. Molly Shannon guest stars as Frankie's sister on "The Middle" at 8. "The Neighbors" offers its season finale at 8:30. Mitch helps Lily deal with a school bully on "Modern Family" at 9. And Dallas learns that Dalia is a hoarder on "Suburgatory" at 9:30.

6. On the dramatic front, Fox is promising that big things will happen on "The Following" at 9 p.m. Monday. "Justified" serves up a new episode at 10 p.m. Tuesday on FX; that series' season finale will be April 2. Katie Couric plays herself on "Nashville" at 10 p.m. Wednesday on ABC; Rayna (Connie Britton) appears on the "Katie" show to discuss her life. "Revolution" returns to the NBC lineup at 10 p.m. Monday. Fans will be happy to see it, but will they be happy about a shocking plot twist?
