According to Variety, OUAT is “staying alive”:
ABC
Dead: “Notorious,” “Conviction”
Mostly Dead: “Imaginary Mary,” “The Catch,” “Secrets and Lies”
Staying Alive: “Once Upon A Time,” “American Housewife,” “Black-ish,” “Speechless,” “The Goldbergs,” “Fresh Off the Boat,” “Designated Survivor,” “Quantico”
Too Close to Call: “Agents of SHIELD,” “Dr. Ken,” “The Real O’Neals,” “Last Man Standing,” “American Crime”
Hasn’t Premiered Yet: “Downward Dog”
“Once Upon A Time” is also a sure thing. Insiders say offers have already been made to the writing staff, which will be tasked with
taking the show in a new direction with the loss of some original characters in Season 7.
Granted, this still doesn’t mean an official decision has been made, and some of these are eyebrow raising. Really, they’re considering renewing Quantico? Variety has gotten things wrong in past predictions, too:
