Brain dead

"Veronica Mars" creator Rob Thomas returns with another quick-witted heroine in "iZombie," a dramedy that proves there still are some clever ideas to be had about the walking dead. Rose McIver, who plays a mortician who can channel the dead after eating their brains, is a star in the making. 8 p.m. WUCW, Ch. 23

One big mess

The biggest head scratcher about "One Big Happy" is trying to figure out what Ellen DeGeneres is doing as one of its executive producers. The mindless sitcom about a gay woman (Elisha Cuthbert) who gets impregnated by her best friend (Nick Zano), just as he announces he's getting married to a British woman, is full of lame lesbian jokes. 8:30 p.m. KARE, Ch. 11

Will & Gracious

Eric McCormack never really got his proper due as a schizophrenic neuropsychiatrist in "Perception," the series that is airing its finale after three seasons. Maybe the cancellation means that co-star Rachel Leigh Cook will have more time to spend in her hometown of Minneapolis. 9 p.m. TNT
