I'm at about episode 10 and running out of steam. It seems to me like they had enough of Bushmaster for about 8 episodes (not the full 13), and it doesn't quite have the same momentum with some of the characters from the first season. The first half of the season is definitely worth the watch, and you'll know pretty quickly whether or not you want to continue.
I kinda liked Luke Cage better as a supporting character in Jessica Jones.
BTW, agree 100% on Reg E. Cathey. He gets more screen time as this season goes on (which is a plus).
