As viewers will undoubtedly remember in the wake of the wild Season 13 cliffhanger, CBS actually took its time in renewing Criminal Minds for Season 14, leading to some concern that the show would get the axe and we would never learn what happens next after the cliffhanger.
At the time, showrunner Erica Messer stated that Criminal Minds frequently got a late renewal due to a variety of reasons, and they were simply waiting for the official go-ahead with the actors, producers, and writers already lined up.
She specifically mentioned delays sometimes due to actor renegotiations and issues between CBS and production studio ABC.
Now it seems her confidence may not apply to the show beyond its fourteenth season.
