Having just finished it a few minutes ago, this definitely felt like the most humane of the Marvel Netflix shows. Perhaps it's the subject matter, the degree to which we see war and how it affects soldiers, Lewis' struggles, Frank's recurring nightmares, Madani's investigation and how Stein's death impacts her, Micro's family, it's all powerful stuff.
And while I like Krysten Ritter, Mike Colter, and Finn Jones to an extent in their respective roles, Bernthal is the first of these lead roles since Charlie Cox who convincingly carried this from start to finish. That isn't to downplay Ritter, Colter, or Jones or to say that they're bad, but Bernthal's performance just resonates with me a lot more than those three did.
Plus, love that Karen was used sparingly. It would've been easy to weave her into the entire season or just bring her in and not do much. She wasn't a 'Claire is in Iron Fist just because' sort of situation. Granted, it's too easy to have Lewis mail that letter to her in particular because of her connection and she's an established character. I mean, does anyone else at that newspaper actually write stories?
But that aside, solid season.
