The entire series was one big "yo, this guy knows magic? thats craaaazy" reaction. Like it was ashamed of it's own source material and never got past it. They kept doing that disbelief nonsense up until the end, so it feels like the actual gang dynamic never got started.
All 4 of them added nothing interesting or of variety in the action scenes. Elektra's motivations are vague and contradictory and Sigourney Weaver is wasted to repeating a couple of cliches. The interactions were like cookie-cutter Avengers and the final episode was a big joke.
