Sunday TV: 'The Comeback,' 'Nanny Cam'

Nanny Cam

Lifetime, Sunday, 9 ET/PT

Something tells me Lifetime was counting the hours until TV's Christmas-cheer break ended, so it could get back to doing movies like Nanny Cam. Well, happy days are here again, as a working mother with a hidden camera learns that her new teenage babysitter is determined to seduce her family and destroy their lives. Seems like it would be a very short movie — you see the footage, you fire the babysitter — but no doubt Lifetime has something more complicated in mind.

The Mentalist/CSI

CBS, Sunday, 9:30 ET/9 PT

Come Sunday, CBS is back in the business of solving murders with new episodes of The Mentalist and CSI. Coincidentally, both shows are solving old murders, as their crime-busting heroes decide to reopen two cold cases. On The Mentalist, it's the murder of a military officer's wife; on CSI, it's a 10-year-old murder/suicide.

The Comeback
HBO, Sunday, 10 ET/PT

Popularity isn't everything. Initial ratings for the comeback of The Comeback have been dreadful, but they weren't great the first time around, either. For some reason, people seem to take their time finding this Lisa Kudrow series, which ends its second run on Sunday. Should you eventually do so, you'll discover a show that can be hard to take, and a performance that is hard not to embrace.
