Marvel's Agents of S.H.I.E.L.D. got a fairly slow start that left a lot of people cold. The initial reactions were positive to mixed, with a bit more "meh" as the pilot's followup episodes rolled on. After such a warm reaction to the Marvel Cinematic Universe movies that preceded it, the show had a lot to live up to. However, it's a bit of a "backup story" by nature. It was never going to have the juiciest of juicy fan-pleasing Marvel spectacles, but some viewers might have expected a bit more. I've seen it put it this way: the show we got is less "marvel at Marvel" and more "NCIS: Marvel." I suppose it's understandable if people were a bit let down.
