Spoilers to follow, if you didn't see this week's episode.
This article on Tor.com really gets to the heart of my problem with the series so far. I enjoy it well enough, but I don't consider it must-watch TV yet. It's too generic an action show. It doesn't really feel like part of the Marvel-verse. I kept hoping Captain America or Iron-Man or someone would swoop in at the end of the episode and rescue Coulson, because... Coulson! I get that they wanted the show to be about the non-super-powered beings at SHIELD who take care of the stuff the Avengers, et al, can't, but by building the show around Coulson, one of a very few non-powered beings who is connected to the Avengers, means not having those super-powered beings be part of the show in some capacity makes for a dull show, especially at the slow pace the mysteries of Coulson's death and Skye's parents are being played out. In addition, as a cliffhanger, this was dullsville. I'm betting tonight's Arrow will school SHIELD on how to do a mid-season cliffhanger/finale (and when did mid-season become a thing?). Arrow started as a show about a non-powered hero and has kept powers out of the show, until slowly introducing them, probably with the Flash tonight, but maybe later on, yet has moved storylines in 2 timelines forward at a pace that keeps ratcheting up the tension/suspense without defusing it, feeding us info at just the right times. SHIELD feels old hat while Arrow feels fresh and exciting. The folks behind SHIELD could take a few lessons from the folks running Arrow.
