I really liked the movie, but keep in mind that I'm not necessarily the most objective MCU critic out there. Strengths were the acting from the leads, the family dynamic, and especially Florence Pugh. I can't wait to see more of her going forward.
The movie definitely felt like an older MCU film for better and for worse. Even though I really liked the opening credits montage, I was thrown off by it. When is the last time a movie like this had opening credits? Sure, both Deadpool films do, but those are played totally for comedy.
I found myself almost laughing at some of the action Widow (and other regular humans) not only survived, but barely were injured during. I can let that go being a superhero action movie, but there were at least five times I said out loud in the theater, "Yeah, that would've killed her."
Whenever I rank the MCU films, I have a pretty static bottom five (which I still love), a rather set top ten, and then all of the middle films, which can switch position daily depending on what I've recently seen or thought about. This falls squarely in that middle group.
It was nice to see a "smaller" MCU movie again, but at the same time, it's tough when you follow the run up to Endgame.
