I didn't watch Daredevil but other than knowing more about Kingpin, I don't see as it has very much bearing on Echo.
Anyhow. The Echo series feels sort of like a sequel adjacent to Hawkeye, as it picks up pretty much where the Echo character left off in that show and follows here forward while simultaneously trying to flesh out her backstory. While there were positive elements, on the whole, I thought the show suffered all the same weaknesses of most of the shows Disney is doing in both Marvel and Star Wars. Its like they don't know the difference between a TV show and a movie and can't decide which they want to be in the first place.
The result is that all of these shows feel both too long and too short at the same time. Too short and too light on plot to be as immersive as a TV show and too overstuffed and long to be a cohesive movie.
They've set up all these young, next generation heroes too... but have yet to do much with them. And now I hear that She Hulk season 2 isn't happening... which is probably for the best. They definitely should continue building these youngsters up as "Young Avengers" or whatever. The old generation is mostly gone, and even if Chris Evans and Robert Downy Jr eventually come back, eventually, if you hope to keep this thing going, you have to have new characters to carry the torch.
She-Hulk was mediocre, but that doesn't mean they shouldn't keep trying to build her up, if not in a second season, then definitely through appearances elsewhere. That's how you build a universe or franchise. We've got to get away from this thing where if the first try isn't a hit then something gets abandoned or completely rebooted in a few years. There has to be room to grow.
