My beef with DD is that it's really stereotypical of the gangs, pretty much to the point of bigotry. The Russian brothers have an exaggerated accent, the Irish gang (for the two minutes of screentime they had) were every single Irish hooligan fused into one stereotype. It's also pretty racist with Gao and Nobu having less depth as characters and every foot solider of the Hand being Asian ninjas. There are some token characters put in like the ethnic rainbow lead by Alexandria and Colleen fighting with Iron Fist but it's difficult to suspend the disbelief.
JJ is a fun show but the overt feminism is sometimes a little too in your face. Everything about JJ and Killgrave is an allegory for an abusive relationship and that's fine to have it written that way but JJ's attitude is almost strawman. She's a "strong" woman but, like I said, it's as subtle as an atom bomb. People say it's a smart show but it's just sort of fast pace. JJ's job revolves around finding out how shitty people are because she expects no better in people. That part of her character is fine to me but it's Flanderized.
All of the Marvel shows have every day people acting like agents from The Matrix. They're all either scumbags or secret ninjas in disguise. JJ and others can just talk or punch their way out of any "normal" problem but they can't go to any hospital or cop because someone's gonna turn into an agent/ninja. The dialogue is also a bit pseudo-intelligent and obnoxious at times. The minor characters like nurse Temple and Hogarth keep coming in contact with the same, few people which is virtually impossible by chance but this is a common trope in fiction.
