Honestly, I don't love that it is going back to being a "Hard R" style show since Hawkeye wasn't. I don't really like that they mix this in with the MCU. I didn't mind it so much when it was siloed on Netflix, but for some of those characters it never really worked. Daredevil for example isn't usually that serious, and a more fun version of the character would be welcome. They were high-quality shows, but really it's unecessary to use certain characters with that tone. Jessica Jones, Punisher - those make sense, but Daredevil and Iron Fist ar emore "superheroey" if that makes sense.
Echo also wasn't a very likeable or sympathetic character in the Hawkeye series. Normally I would give the benefit of the doubt to the MCU folks, but their TV output has been less than stellar. Couple that with my general lack of interest in the character, and I may just give it a pass.
