Watched this over the weekend. Enjoyable with a lot of great things to it, but I think it's the weakest, or second weakest, Marvel season so far, and I actually like Luke Cage here quite a bit unlike his rather poor showing in JJ.
For me I'd say: DD>JJ>LC=/>DD2
The whole overarching plot was pretty underwhelming, characters were all pretty universally good, except for the main villain. Diamondback and that whole twist was just terrible and cheap feeling. Far too cartoony. Cottonmouth, Shades and Mariah were better, but rather mehh adversaries though for a man who is invulnerable, but they were at least, especially Cottonmouth, somewhat interesting. Not that a corrupt city councilman with a underworld relative is all that frightening and original. Misty is just a terrible cop. Pops was cool for about 5 seconds until it was abundantly clear he was going to get murked for the sake of Luke Cage's destiny.
Action was honestly kind of bad. The only really good sequence was when the dude punched him in Genghis Connies and just mutilated his hand and forearm, everything else was rather ho hum. Especially compared to the pretty great fight choreography in DD. They just never really did anything interesting with the fights to showcase Luke's powers. Great you shoot up his clothes every episode, gets old.
JJ was probably the weakest actual overall structurally because it was about 50-60% filler, but the main conflict was the best so far. Mr. Purple and his relationship with Jessica was the best by a long shot, it just wasn't enough to fill out 13 episodes and so you had a lot of pointless stuff happen in between. Like Luke Cage.
DD1 was the overall strongest, but season 2 got a case of the stupids at times and the whole supernatural aspects just felt off by the end. Also the DD suit is the worst thing ever.
I am interested to see where they take Luke. A bit underwhelmed that Mariah and Shades are still at play. The doc of course has his research info; welcome back actually super powered Diamondback.
