Being a comic book fan for over twenty years, brings big expectations when the industry announces a new television show is coming. That said, everyone should try to give this show some slack. Yes, media darling Joss Whedon is running the show (alongside Executive Producer Jeph Loeb), and the show has the backing of the billion dollar Mickey Mouse. These don't have to be reasons to crucify the show for not being spectacular so far.
The last episode that aired before the winter break, brought more comic book characters into the T.V. universe with edition of Deathlok. Also, one of the main cast members was shot and at deaths door to give us a cliffhanger and entice the viewers to return. Fast forward to March 4th, and the next episode. The show was very exciting, because it showed more of what is going on behind the scenes with Coulson (Clark Gregg), and even brought the journeyman actor Bill Paxton into the fold (albeit for one episode apparently). Paxton's character was very cool and added more back-story to the show itself, and specifically Coulson and Agent Ward (Brett Dalton).
The preview for the next episode is bringing some of the elements of the Thor movie franchise aboard, but one must wonder if this is just a ploy to get more viewers or actually has something to do with the ongoing subplots of the series. Viewers need to have faith in not only Joss Whedon (Buffy the Vampire Slayer, Dollhouse), but also in Marvel's television studios as well. These guys know what they're doing and have a track record on the big screen that second to none. It might be a long first season due to an extended plot, but give it a chance because the creative team seems to be heading in the right direction...for now.
Marvel has been moving their television and cinematic universe away from mainstream comics continuity for a few years now. They follow more closely with the Ultimate Universe, than normal continuity. This is something some long time fans have a hard time adjusting to, and rightly so, but in the end, most are happy just to see their heroes jump off the pages of their favorite comics, and onto their flat screen televisions!
