I enjoyed the movie a lot. The writing in particular is fantastic- self-aware, clever, deft, fast-moving without being weightless. I don't entirely feel like I can compare it to other Spider-Man movies or even other superhero movies because it's so much its own thing. It so embraces the idea that you're already well aware, if not overly-aware, of Spider-Man and his backstory that it feels like putting it above other movies would be like downgrading the required reading without which the focus wouldn't exist.
Treading lightly, I also have to suggest that a lot of movies could stand to learn a thing or two from "Spiderverse" about how to create and celebrate diversity without bludgeoning its audience with it. The original Peter Parker is only on the scene briefly- long enough to establish him as a little arrogant but basically a likable and good-hearted man who loves being Spider-Man. He's the first one to show any faith in Miles, and immediately expresses both interest and willingness to help and teach him; he's not threatened by his existence, and indeed seems thrilled by the idea that there might be others like him.
It's a theme throughout the film, really: There are others, like me but different, they're great in their own different ways, and it's a good thing.
It didn't need to mock or downgrade Peter Parker to pump up Miles Morales. It didn't need Miles to be without flaws or doubts in order for him to be a hero. It was aware of race and gender without having to constantly turn everyone who didn't check a certain number of diversity boxes into a villain or an ignorant ass in dire need of lecture, enlightenment, and the guiding hand of imminently enlightened minorities. Character flowed from more than needing people to serve as examples or exemplars.
It does it, and so many other things, so well, and makes it seem so easy, that it kind of makes me go, "Damn! Why aren't more movies doing this?!"
