Man, looking at all the rankings, I have to ask: Am I the only one who doesn't hate Agents of S.H.I.E.L.D.?
I like AoS more than I like Daredevil, but that's not nessisarily a slight at DD. I'd say technically that DD had very few objective faults (the lighting, some pacing issues, the poorly written exposition) but it just happened to hit a lot of my personal dislikes:
1. Constant violent fighting - yes, I know that's part of what makes it so popular with others but I'm not a visual person and fighting tends to be all eye candy so I just get bored. My favorite thing about fight scenes is one liners, finishing poses, awesome pre-action shots, and quick beats that are only there to serve a character point rather than being about the actual fight none of which are actually part of the fighting and none of which belong in a gritty crime drama ala Daredevil.
AoS and the Marvel Movies, on the other hand, seem to live on this trope. I love it.
2. A poor balance of vigilantism/procedural; like Matt are you even really a lawyer dude? People get tired of SHIELD going out on missions of the week or dealing with other SHIELD like groups and corporations but considering that is SHIELD's job, I'm pretty okay with it.
3. The use of Urich, Karen, and especially Foggy where I feel like their idea was to show that although Matt is surrounded by friends and a support system that would do anything they could to help him, he felt that this fight was his responsibility and so he isolated himself. That's all fine, I actually love that theme. Only it works better if you see what the other characters bring that could help Matt that he was losing out on because of his self isolation. I don't really feel like he suffered all that much for leaving them out of it. He suffered, sure, but most of it was because of stuff they wouldn't have really been able to help with in the first place. The stuff they could help with, they helped with regardless. Plus his forced separation means that for long stretches of the show the Foggy/Karen scenes seemed unrelated. Which I didn't mind as much as others - I love a big cast on shows and don't always have to focus on the main character - but it clashed with what the show wanted to do which is the reason some people didn't like those scenes.
4. There is thematically, dramatically dark and then there is gritty, reality-is-hell dark. Almost any time you have one you automatically engage the other, but usually you lean one way or another. Jessica Jones leaned towards the thematic, and I personally prefer that. DD leaned towards the gritty. There is nothing wrong with that, I just don't personally find it very engaging.
5. Actually, I failed to find most of the characters engaging. I liked Wes and Foggy and Urich. So... that turned out well for me. But again, this is entirely subjective and personal.
AoS has a huge cast, and I'm very much so a character person. I don't know how many times I've mentioned it but if Avengers 2 had just been Joss writing two hours of those guys hanging out at Avengers tower I would have eaten it up. They tend to do a little more than sit around playing Xbox (although there is that!) but the cast on AoS is constantly interacting and I find most of them engaging (although not Lincoln... Lincoln is easily the worst.)
So just because of my personal preferences I really loved AoS despite it's many faults and missteps, where as most of DD just failed to click with me even though I appreciate how well received and much loved it is by the community.
