I just recently finished Iron fist season 2 and I have to a agree it was rather mediocre. I'm not too familiar with the content of iron fist so to me its all-new concepts but I felt like nothing was on the line in this season, the story didn't offer me much or further my interest in the origin of the iron fist

I also wasn't a fan of how quickly people just master the ability of the iron fist. I mean Danny could bearly use it once and he'd be drained now anyone can just pull it out on a whim. I'd be fine if you explained to me that they have better control over their chi or had better training but everyone was just iron fisting left right and centre

I did like the addition of Mary she brought with a different dynamic but as you said was awfully harely quin in a way.

Overall I was disappointed! The last Marvel series I enjoyed was the punisher. Hopefully its set right again with the series that started it all, Daredevil!
