TLDR; It's a great series and a nice change of pace from other Marvel properties.
I'm loving this series, so much so that it might be my favorite one on Disney+ currently. It's heavily inspired by my favorite comic book series of all time (Hawkeye by Matt Faction and David Aja), which makes it feel a lot closer to me than any other Marvel story, so I know I'm very biased. Nevertheless, it's a great story because it's not as "large" as others, it's doing a good job at staying grounded, rather than pushing us in a lot of different directions or locations and giving us visual whiplash (and being left trying to figure out what the heck is really going on in the story).
There's a mystery but it's not involving a million moving parts, it's actually very reminiscent of the older Netflix series (which I also loved), and it's giving me a little bit of nostalgia while also feeling like something new entirely. I already love Jeremy Renner and his portrayal of Hawkeye, and Hailee Steinfeld is doing an amazing job and is a very fitting actress for Kate Bishop. I'm so excited to see more of this series!
