Don't go looking for "Quantico" anymore.

Only a few weeks into its third season, the spy thriller was abruptly yanked by ABC. Look for the summer season "news" distraction "What Would You Do?" (10 p.m.) to air in its place.

While every canceled series fails for unique reasons, certain trends have emerged.

This year has seen network viewers cool to thrillers set in the spy game, as well as shows featuring political intrigue and deep-web skullduggery.

Along with "Quantico," ABC has canceled the alien-invasion-from-the-future conspiracy thriller "The Crossing."

This season saw three new dramas covering the shadow world of special ops and undeclared wars.

Of the three, only "SEAL Team" on CBS has survived. The CW's "Valor" and NBC's "The Brave" never found an audience.

"SEAL Team" had the benefit of a CBS audience receptive to hyper-violent procedurals.

But not even CBS viewers could put up with "Wisdom of the Crowd," a show about crime-solving through crowd-sourcing that quickly vanished.

There will be fewer shows set in a scandal-plagued White House next season.

"Scandal" is gone, and so is "Designated Survivor." Curiously, "Madam Secretary," which seemed to be based on a former secretary of state and reflect a bygone political era, has been renewed.

Series set in the TV business are always a hard sell. Not even Kyra Sedgwick could save "Ten Days in the Valley," a missing-person drama revolving around a TV writer/producer.

And Tina Fey's "30 Rock" touch was not enough to save the network newsmagazine comedy "Great News" on NBC.

Fox has renounced Satan and all of his pomp, canceling "The Exorcist" and "Lucifer." Viewers also rejected the angelic head-scratcher "Kevin (Probably) Saves the World" and the sitcom "Living Biblically."

This has been a bad year for shows with "Kevin" in the title. In addition to ABC's canceled "Kevin (Probably) Saves the World," CBS issued a pink slip for "Kevin Can Wait."

Audiences recoiled when that series killed off Kevin's wife, played by Erinn Hayes, so he (Kevin James) could spend more time with another woman (played by James' "King of Queens" co-star Leah Remini). Casting gimmicks can be murder.
