It's a bit weird. It's fully centered around the awkward relationships between everyone, completely about the characters with just a bit of "let's stop the Hand from doing whatever they're doing" because what the Hand is doing isn't actually important. I'm not quite done with it but it looks like there's no demon, no dragon, no grandstanding, just the Hand trying to reach a goal that turns out to be very tiny and dumb, but somehow threatening to blow up the city over it for some reason. And because it's more about the relationships and the human side of everyone (even the Hand), it means there's a LOT of talk. That may not be for everyone's tastes, especially if you were hoping for some massive fights and city-wide battlefields.
Personally, I'm fine with how this is basically just having fun between the main characters of the previous series, but I'm sure this is definitely not what people were looking forward to. Actually, it kinda feels like the previous series were, just an introduction to the big name but nothing really important, this is just introducing the team-up... Which is bound to disappoint a lot of people.
The fights are a lot shorter, but they're intense enough, and while they're not amazing, they're well done enough, with better execution than the other series - if only because there are more parties involved, as in the 4 main guys who move independently but it still harmonize well.

edit - hmmm never mind I'm at the end of episode 7 and I might have said the "no dragon" bit a little early (still 7 full episodes out of 8 though)... although whatever it is is irrelevant to the rest of the series.

edit again after ep 8
Eh, after half an episode foreshadowing Daredevil disappearing, I was expecting it to open the path to some Shadowland-like story arc. Oh well.
So anyway, we've got Steel Serpent for Iron Fist S2, Daredevil is already moving on to something else, Jessica is back in business, and Luke may lead to some Hero for Hire story at least in the same capacity that Luke showed up in Jessica S1. Punisher S1 is for the end of this year, what's for next year ? At least Jessica S2 I guess ?

One more edit
Uh hang on, we never did learn what the fuck the black sky was a prophecy about... If it was just brining the Iron Fist to the gate, couldn't anything have been fine ? And clearly we'll never get an answer.

Not killing Matt for real feels pretty cheap and robs a lot of solemnity from the end :I

I get the whole Kingpin getting out jail and running NY now that the hand is gone (unless Gao survived too) needs to be wrapped somehow, but I thought that's what Punisher was supposed to do?

I like how the we finally got an explanation on how the Hand worked and the relationship between Gao and Bakuto, and how Nobu was lower on the pecking order. But even then we don't know why the Black Sky was so important and why if Alexandra thought Elektra was some God-sent weapon a mook like Nobu had one of his own (the kid Stick murdered in DD S1).

Also, Harold Meachum came back after having his body destroyed by cancer, but Alexandra's disease is somehow worse than that?

I did not expect that ending for Episode 6 at all, but with all the infighting not only with the Defenders, but the Hand leaders it was going to come to that eventually. Alexandra from what she said was killed by Madame Gao leading an rebellion to kick her off the seat as the top Hand leader. Elekra is now in charge, but will Daredevil be able to kill her off I'm not so sure. Another good and surprising thing I like between these two Episodes was Wing's Sensei returning! Wing vs her Sensei was one of my favorite fights in the Iron Fist show and now he's back so I look forward to if she finally kills that man. It's her destiny to finish him off.

Dat tease though with Daredevil being alive, I expected him to survive, but where is Elektra and where is he as well? Oh well the big fight with the Hand vs Defenders was great. I loved the action throughout that fight each of them had their moment to shine including Colleen killing her Sensei, as Misty lost her Arm to set up her Bionic Arm like the Comics good to see them use that going forward for the future Luke Cage Season. Luke kinda having a moment with Jessica hmm wouldn't it be interesting if he got with Jessica and Claire finds out oh boy. I can't wait to see what they have planned for Daredevil after the ending scene in this series, don't know enough of his Comic Book history to see what's going to happen, but I'm pretty damn psyched for it. Iron First in this show>Iron Fist solo show for me. He was truly bad ass and to me he got alot of character development that they should of given him in his own show. With Madame Gao still alive, his thirst for the Hand to truly die continues and Season 2 for his show should be in a vein of this show I hope. Jessica Jones seems to understand what her role is truly in live right, which was a different thought in her mind in the beginning of the Season and it was the death in her mind of Daredevil that changed her. He gave his life to protect the city he loves, so it's time for me to do whatever it takes to protect this city as well.
