Eh, I saw the pilot. Based on what I know of the series, the primary hook was that it was going to fill in the plot gaps between Marvel movies, which was abandoned. It was going to introduce and promote things like Inhumans that were going to advance the films, which it didn't. It was always going to be a longshot to get film level SFX and anyone big from the movies. Heck, Shield was disbanded halfway through the first season, so If anything, the series was mostly hurt by the films and rarely helped. So, the whole series? No, but select episodes seems reasonable. Like the treatment we should all give the first season of Star Trek series.
I watched the first season. I was really bored with it and forced myself to finish the first season. I didn't have enough interest to watch any further, although I hear other people say it got better after the first season.
