I think I've figured out why I like Arrow more than S.H.I.E.L.D. It's not that Arrow is any less stupid, it's that they keep the always keep the plot moving forward, always keep things suspenseful, so you don't have time to dwell on how stupid one particular plot point is.
Plus on Arrow, I actually care about the characters. Even some of the bad guys. Even Laurel. Sometimes. But SHIELD has not made me care about any of the characters other than Coulson, and frankly, he started the show with that. I like Melinda May. She's such a badass. But I don't know that I care about her, not really. And the rest of them? Fitz and Simmons are cute but...whatever. Ward is boring as shit. Even sleeping with Melinda May didn't improve him. And Skye is annoying AND boring.
Make me care about the characters, and you can do a bottle episode where they all look for a pen on the plane for the entire episode, and I will love it. Give me characters I don't care about, and...enh.
(We just watched last week's episode, so this was my first chance to comment. I liked the narrative structure, although I confess I was hoping for more of a Rashomon effect. I do actually like Ian Quinn. And I like Mike Petersen, poor bastard. But none of the episode really made me give a damn about the characters.)
