Let me forward this by saying that I am a long time Marvel junkie. Love the comics, love the movies, desperately WANT to love this show but...
I really can't understand why Marvel is wasting such a great opportunity to try out new characters that could go on to be new movie franchises. Why couldn't they have re-tooled the script a bit and made "Scorch" into "Sunfire" or some existing character? Why Couldn't the first Extremis subject from the Pilot have been an existing character? Sure, "because those characters in the show died" is a valid argument, but they didn't have to die. That's what I meant by re-tooling. Look at Smallville and Arrow. Those show have a universe generally grounded in reality and they actually care about their fan base enough to throw them some cool little geek moments like when Arthur Curry shows up or the mysterious assassin turns out to be Deadshot. Quite frankly, other than Coulson and May I really couldn't care less about the rest of the team. I agree that they might just need time to gel with the audience, but...there isn't going to BE an audience if you don't give them a reason to keep tuning in. The whole Extremis thing is cool, but there's got to be more than that out there for S.H.I.E.L.D. to investigate. Hell, Iron Man took care of that in that little movie thing that he had going on a few months back. Give me HYDRA!!! At least give me some bad guys in green body armor and red goggles so that I can pretend it's HYDRA. Give me some low rent bad guys like Batroc the Leaper, Gorgon, or Scorpio. The team ,as it stands right now, CAN'T carry this show. I want it to keep going on and every new episode that comes out just frustrates me even more. Joss Whedon's name can only keep a show alive for so long. Look at Firefly. That was an AMAZINGLY GOOD show and it got cancelled. This show needs some emergency damage control bad assery injected into it soon or it's going to be another failed series that could have been great.
