10 TV Shows In Danger Of Being Cancelled
3. Agents Of S.H.I.E.L.D.

Why it Might Be Cancelled
For its fourth season, Marvel's Agents of S.H.I.E.L.D. moved to a later timeslot and promised a darker run. It's delivered that, but it has also meant losing roughly a third of its audience, dropping to just over 2 million viewers and only 0.75 in the key demographic. ABC has Inhumans starting in the fall, which they might see as this series' replacement.
Why It Might Not
Inhumans' first season is only eight-episodes, so they might keep S.H.I.E.L.D. around to give it an obvious lead-in show. Plus keeping it around means they have more ties to the Marvel brand, which can't be a bad thing. The show is also picking up some real steam and critical love with its current Agents of Hydra run, which might help convince network chiefs to give it a final outing.
