Need a break from March Madness? Here are a few options. (If you’re a true NCAA basketball fan, though, you probably won’t have time to watch anything else this week.)

SUNDAY

“The Walking Dead” ends its second season tonight on AMC. It’s a great time to catch up since AMC is running a marathon leading up to the finale.

Also Sunday, the stunning “Frozen Planet” begins its seven-episode run tonight on Discovery and TLC. If you don’t already have a high-def TV, this is an excuse to buy one. Or maybe to upgrade to a bigger model.

MONDAY

“Dancing With the Stars” (8 p.m., ABC) returns with a two-hour kickoff. Former “Melrose Place” and soap actor Jack Wagner, tennis great Martina Navratilova, “Little House on the Prairie’s” Melissa Gilbert, one-time Urkel Jaleel White, Gladys Knight (who needs no other intro), the requisite athlete Donald Driver, Maria Menounos of “Extra”, singer Gavin DeGraw, the “View’s” Sherri Shepherd, Latin heartthrob William Levy, Disney Channel’s Roshon Fegan and “classical crossover artist” Katherine Jenkins. I admit it… I had to look up  a few of those “stars” to see who the heck they were. (I’m talking about you William, Roshon and Katherine.)

WEDNESDAY

Romantic comedy “Bent” debuts with back-to-back episodes (9 p.m., NBC). It stars Amanda Peet as a newly single mom, and David Walton as the contractor she hires.

FRIDAY

“In Plain Sight” airs the second episode of its final season, with Mary dealing with a baby and a hoarder who witnesses a killing.
