As far as pilots go, I found this lukewarm at best. The few familiar faces in the ensemble cast (Swan, Leung, Rheon) didn't do much to elevate this episode much above the pedestrian, unfortunately.
Action? Nothing much to speak of. Plot/intrigue? Rudimentary. Writing/dialogue? A catalogue of "You-should-have-been-mine" and "How-very-dare-you" clichés. CGI/FX? Embarrassing. Queen Medusa's hair looks like it was copied and pasted from Jessica in "Who Framed Roger Rabbit?", Gorgon's hooves look like he picked up some theater prop hairy pants at the dollar store, Iwan Rheon stars as Ramsay Bolton starring as Maximus and proceeds to "Reek" the entire population of Attilan, and our parting impression of the mighty Black Bolt is essentially as a mute in a suit, and a hapless one at that. Lockjaw is the Royal Family's teleporter, but serves mainly as comic relief.
Being a fan of Marvel doesn't save this from being dead in the water. It feels like various studio execs are simply milking Marvel for all it's worth, adapting any team or hero possible to the screen in order to turn a profit, with scant regard for their craft. I'll slog through this season, but with exceedingly low expectations, and am unsurprised to learn that it never made it to a Season 2.
