There's a big possibility that Marvel's "Agents of S.H.I.E.L.D." season 5 might not even happen due to the show's low viewership. But Marvel TV Head Jeph Loeb is "hopeful" that ABC will renew the series, which will wrap up season 4 next month, for a season 5.

According to a report from TVLine, Loeb remains bullish about the TV series' chances of a renewal despite only averaging 2.4 million total weekly viewers. The series do have a 0.8 demo rating in Live+Same Day numbers.

The report said that the demo rating allows "Agents of S.H.I.E.L.D." to outrank five other ABC dramas. Marvel's TV series also bumped its DVR playback to 113 percent, which is second only to the 126 percent that ABC's "Designated Survivor" and "Quantico" currently enjoy.

The real problem, though, lies in how the series started. "Agents of S.H.I.E.L.D." started season 4 with 3.4 million total viewers and a rating of 1.1. But the numbers gradually went down as the season progresses and it reached its low point in mid-February when it drew only 2 million total viewers and had a rating of 0.6.

The low point was also the climax of the series LMD arc, which meant there was fewer people interest even in the climax moment. The new arc, which is about the "Agents of Hydra" pod, has somehow bumped the numbers to its current figures, but this bump could possibly be a little too late.

The series is above only "Time After Time" and "American Crime" when it comes to the TV series that draws fewer crowds. But GameRant reports that it's still possible for "Agents of S.H.I.E.L.D." season 5 to happen and this could be enough to bump up the series numbers.

But it will be hard, considering that the popularity of the show has been dwindling since the series began. The report said that the "Inhumans" property coming to TV also didn't bode well for the series' future.

But with MCU as popular as ever and Loeb's confidence in the series, it might be enough to convince ABC to make "Agents of S.H.I.E.L.D." season 5 happen. Check out the promo for episode 19 of season 4 in the video below.
