Joss Whedon talks S.H.I.E.L.D. TV Show:
So far it's exactly what I've been expecting...
"It's new characters. It needs to be its own thing," said Whedon. "It needs to be adjacent [to the movies] but you don't want to do a show where you're constantly going, 'Iron Man just left, but he was totally here a minute ago.' You want them to do their own thing."
Whedon also clarified what exactly 'their thing' is, "Well, what does S.H.I.E.L.D. have that the other superheroes don't? And that, to me, is that they're not superheroes. But they live in that universe. Even though they're a big organization, that [lack of powers] makes them underdogs, and that's interesting to me."
