iZombie (9 p.m., CW) – Finally, a new twist on the zombie TV genre: In this new series (based on a DC Comics book series), a zombie helps the Seattle police solve murders by experiencing the victims’ memories when she eats their brains. In the first episode we see medical resident Liv Moore become a zombie and lose her ambition (becoming a zombie will do that) until she begins working at the city morgue (you know, access to brains). That’s where she learns that the brains allow her to experience the victims’ memories. One of the creators is Rob Thomas, creator of “Veronica Mars.”

Also on tonight . . .

Rizzoli & Isles (8 p.m., TNT) – Two new episodes close out Season 5 tonight. In the first, the squad tracks a sniper and in the second, a murder victim is discovered to have been living a double life.

Undateable (9 p.m., NBC) – I loved this sitcom last year, so I’m happy to see it back on the schedule. In tonight’s Season 2 opener, Justin tries to have a one-night stand, but it doesn’t work out. He also hires a new bartender, which also doesn’t turn out well.

One Big Happy (9:30 p.m., NBC) – A terrible new sitcom about two thirtysomething best friends since childhood who decide to have a baby. But then one of them suddenly falls in love and gets married. NBC was nice enough to send a bunch of episodes, but I had “life is too short” moment halfway through the second and bailed.

Perception (10 p.m., TNT) – In the show’s series finale, Moretti goes missing on her wedding day and Pierce discovers she’s been abducted by a dangerous person from his past.
