Oh, wow. I didn't realize it was dropping this soon. I hope it's decent.
I'm cautiously optimistic, but not holding my breath after my disappointment with Secret Invasion.
Apples / Oranges. The thing about the MCU as a franchise is that between films or shows, there are different creative teams involved, although there is some crossover every now and then. Unless the thing that made SI awful came from the top down, I doubt whatever disappointed you about SI would have any bearing on ECHO. If anything, ECHO's connections to the Hawkeye and Daredevil series should alleviate any suspicions that this might turn out bad. If anything, it might be serviceably good at worst, and a sure-fire hit at best, but like you, I am still cautiously optimistic. I just think SI was an aberration compared to every other MCU D+ show so far. I'd take any of the three 2022 shows over it (especially She-Hulk, while not overly groundbreaking or enthralling, was at very least entertaining and also had some fun cameos, like Daredevil).
I think if *anything* hurts this show, it'll be the full-series drop/Netflix method of release. It'll garner about a week or two's worth of online chatter and probably be forgotten, unless there are some big revelations involved. I honestly prefer the weekly-release method that they've done since WandaVision, as it keeps the audience engaged over a period of time. It's not like the MCU is hurting for air-time this year, so they definitely could have spread this out over 4 or 5 weeks. It'll be interesting to learn, later on if it's revealed, why they decided to put this out all at once. My initial thoughts were that they didn't think it was good enough to keep audiences engaged over the course of a month, and figured if they got it out all once, watch times would be greater, but who knows.
Either way I am excited to see something relatively fresh from the MCU. Maybe if I'm bored or have the time to, I may rewatch Hawkeye this weekend as a refresher for Echo herself.
