“Inhumans” is officially over, but it didn’t exactly tie everything up neatly. The season finale showed the fall of Attilan, and the Inhumans decided to start new lives on Earth. Fans might not get to see how their move goes in Season 2, though.

“Inhumans” Season 2 most likely isn’t happening. ABC hasn’t announced that it’s canceled yet, but they made it pretty clear that a second season wasn’t being planned when they promoted the new Marvel show with “see the complete series” in the lower right corner on most of the posters. That implies that the show was a one-time deal.

The ratings are also feuling cancellation rumors. The show averaged about 2.56 million viewers, according to TV Series Finale. While that’s not terrible for a Friday night show, it’s also worth noting that the show declined almost every single week. They only averaged a 0.6 rating in the coveted 18-49 demographic.

“Marvel’s Agents of S.H.I.E.L.D.” fans might notice that the veteran series has similar numbers. Season 4 averaged about 2.3 million viewers each week and a 0.7 in the demo, and yet they still were renewed for Season 5.

The veteran show’s numbers were more consistent, only going up or down a little each week. However, “S.H.I.E.L.D.” fans will remember that renewal was not a guarantee. The show was very much “on the bubble” until the announcement was made. While ratings are the most important, reviews play a part too.

In the final pod of “Agents of S.H.I.E.L.D.,” many critics praised the show. The Framework idea was inventive, entertaining and was a bit of a gift to those who had stuck with the show through the years. “Inhumans” never received any affection from critics. If the show isn’t earning money or critical approval, it’s difficult for the network to find a reason to renew it.

“Inhumans” didn’t just have a network expecting excitement from fans. IMAX had released the pilot in theaters, where it only made $3.5 million. IMAX CEO Rich Gelfond told Deadline that “Inhumans” didn’t meet moviegoers’ expectations in terms of scale.

“Customers expected a production akin to a mega-budget blockbuster movie, rather than pilots for a television show,” Gelfond said. “Moreover, the fact that this was Marvel IP set the bar at a level you wouldn’t see from other pieces of content or IP because of the reputation and the high production value of Marvel movies.”

It’s safe to say that “Inhumans” is likely over, but remember #ItsAllConnected. The Inhumans could easily show up on “Marvel’s Agents of S.H.I.E.L.D.” once the secret agents get back to earth.

“Marvel’s Agents of S.H.I.E.L.D.” Season 5 premieres Friday, Dec. 1 at 8 p.m. EST on ABC.
