Just finished.
It was pretty good
Pros
-I thought Danny and Luke were WAY better here than in their own shows. Especially Luke. Danny I feel like he was a lot better when they gave him personality. Like with him and Luke in the Chinese restaurants. Give him something like that. Build on his kid like nature. Please. I know they're not but they really should do Heroes for Hire instead of LC2 or IF2
-Performances overall were solid
-Most of the action scenes were good
Cons
-I thought Sigourney Weaver was wasted
-For it being shorter, those first episodes dragged on. It took them way too long to come together
-Too much stuff with the side characters. I don't dislike the characters, but it's The Defenders show. I don't care about them when Im trying to see Cage, Iron Fist, Daredevil, and Jessica Jones interact
-I disagree with a point made last page about this feeling like DD3, LC2, etc. I think it was a bit much and I think Avengers (sorry that comparison is just gonna come) did a good job forwarding the story of most of it's characters without taking that full step
-I don't like the Hand. I'm done with them. I don't wanna see them again
-At 2 points the soundtrack choices bothered me. The first when they played Run the Jewels, the second when they played Protect Ya Neck in the last episode. Now I love Run the Jewels (actually saw them in concert last weekend) I own all their albums and some of their solos. And I love Wu Tang Clan, 36 Chambers is one of my favorites. But the placement of the songs were so weird. The scenes where they were featured, used the songs in the most pointless ways. The moments would've been better by using a score
-Danny spent way too much time away from the rest of the group near the end
Fanboy Complaints/Nitpicks That Didn't Affect My Enjoyment But 
-Wish Iron Fist got a costume. There was a chance of a cool moment of Danny geeking out over the costume or at least some kinda scene where Matt tells him how he got it
-Now this is a bulls*** nitpick...but everyone was too layered up. In some of the fight scenes I just sat back and thought: "Why is Iron Fist wearing like 3 coats." "Why is Jessica still wearing her scarf" "Couldn't Luke just be wearing his yellow shirt instead of that hoodie they keep pushing?" Idk...I'm weird
Overall this was good. Nothing crazy. Next time they just need to tighten things up in terms of characters and pacing and also get better villains
