The writers and producers of that show are ashamed of their roots, I am now convinced.
They're frigging comic books, not lost chapters of the Bible. Don't take yourselves so seriously. You're not going to lose 50% of the viewing audience at the first sight of spendex or a cape. It's not enough to give guys clever names, they need a suit and a scheme.
Instead we get schmoes, scientists, and girls in flowery dresses. Big fat hairy deal.
It's not a bad show, just not nearly as good as it could be by injecting the same stuff that made Avengers so wildly popular. In the comics, SHIELD was regularly interacting with super powered heroes and villains.
Red Ronin FTW!
