Saw this today and loved it. Best movie of Phase 4, which I realize doesn't sound like THAT much of an accomplishment, but it's really, really good. (I mean, I loved No Way Home, but that was way more for nostalgia-bait reasons that had little to do with the quality of the movie)
It felt like a true sequel to the first movie, in a way that many MCU sequels don't. But at the same time, it added to the universe in a substantial way, which many MCU sequels also fail at. And my only real issue with the first movie (that lackluster final battle) was absolutely not an issue with this one.
It's crazy, it's almost like if you don't deflate every moment of tension or gravitas with a stupid joke, it really helps you invest in the movie.
