I've watched all of season 2. So my non spoilers for it are that it's great. If you liked Season 1 then you'll probably enjoy season 2.
And now spoilers for all of it.
Season 2 was great. I loved both the Punisher and Elektra. The Punisher's storyline was very good and they definitely left it open to continue in his own series.
Elektra's story was good idk if this Black Sky thing was something from the comics? But her and Matt where really good together. Elektra "Dying" was expected and her more than likely resurrection won't a surprise either.
I thought all the fight scenes where fantastic. The one with DD fighting the bikers was awesome and the one with Frank in the prison was great.
And I liked the added storyline with Stick. And I'm guessing the guy we saw him talking to last season was the guy who started this Anti Hand group?
The introduction of The Hand was good they where the Main Villain of this season and they where done well.
Though one of negatives is I wish there would have one big bad at the head of the Hand instead of Nobu. Seeing Kingpin in the prison showed how much he was missed but they definitely did a good job of setting up Season 3.
And probably my biggest negative was Foggy he really added nothing to story and by the end I felt like he was an afterthought.
But overall really good I liked this season better then season 1 and I loved season 1. So with these 2 seasons of DD and the 1season of Jessica I'd say Netflix is 3 for 3.
