I think the show is setting a solid base of what this unit of SHIELD is doing and what kinda menace they're facing. Each episode is showing a different side to the tech and rubbish the Aliens from the Avengers movie left behind, different things humans are doing with them. I think they have to do this, and IMO they doing it pretty well, not spectacular, but well.
They can push it like ARROW, cuz Oley not only an established hero, he's one of those one man ass kicking machines that, lets face it, is easier to write around...., then a team of "normal" humans, with personal issues n secrets, running spy-ish operations, and adventuring for lost dangerous tech. I understand why people call it a "superhero" show....but its really not.
I think the show is pretty good, im patient with it. Cool action, some fun concepts, not as down on it as people are in here.
