It's better than the first season, but not by much.
Some of the writing is embarrassingly bad. Same with some of the acting.
Finn Jones/Danny Rand isn't quite as annoying in this season.
The "villains" suck. They aren't vicious enough to make you root against them, not interesting enough to make you root for them.
Maybe it says something that I'm waiting impatiently for another Defenders character to show up. Luke Cage, Misty Knight. Claire. Hell even Foggy would liven this shit up (The Punisher would make for the best guest appearance but that will never happen).
Hopefully this will take a surprising left turn in the next few episodes.
