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 Culbert) 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. Then there's the fact that the fiancée (Kelly Brook) seems to be in a continual state of undress. What isn't a surprise is that many others involved in the series are veterans of "2 Broke Girls," quite possibly the most offensive network sitcom in TV history. 8:30 p.m. Tuesday, KARE, Ch. 11

Knock on her door

"Dancing With the Stars" is kicking off its 20th season with one of its blandest casts ever — with the striking exception of "Three's Company" star Suzanne Somers. Now if only the producers could have signed up Joyce DeWitt and the guy who played Larry. 7 p.m. Monday, KSTP, Ch. 5

Brain dead

"Veronica Mars" creator Rob Thomas returns with another quick-witted heroine in "iZombie," a dramedy that proves there are still 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. Tuesday, WUCW, Ch. 23

Building an empire

It's still early in the year, but it's hard to imagine that there will be a bigger success story on network TV in 2015 than "Empire," which wraps up its short season with a two-hour episode. Not only is it the most popular new show of the season, but its viewership has grown every week. More important, it's proof that shows starring people of color can soar. 7 p.m. Wednesday, KMSP, Ch. 9
