It's absolutely astonishing how not only does this not miss a single beat in regards to how much it's juggling in terms of ideas, themes, and characters, but how it always comes back to Miles.
Everything that happens here, even at its most chaotic, always comes back to him. His struggle. His emotions. His hopes. His dreams. His doubts. This is 100% his story, one that couldn't work without him and one that needs these people in it to help him discover it.
These characters aren't here to distract, they aren't here for fan service, they're here because they need to help him, in more ways than they end up believing by the end. Miles' struggle to be himself being pushed down by everyone in his life (both personal and hero) is one that can ring home to a lot of people (especially kids), and it's that struggle and that care put towards it that make "Into the Spider-Verse" so special, beyond everything else that makes it so special.
What Bob Persichetti, Peter Ramsey, and Rodney Rothman have done here is not as simple as you were expecting as quick "make it look like a comic" type of deal you might be expecting, but instead push the boundaries of what the medium is capable of in regards to editing, direction, and visual storytelling.
The way it weaves in completely different ways of showing things with completely different colors, character animations, backgrounds, details in the background, foreground, is absolutely astonishing as you were probably expecting, but it manages to find new ways to surprise and impress throughout its run time, again, not missing a single beat and sticking the landing more than once.
Everyone is perfect as you were expecting, the real scene stealer here isn't Nicolas Cage as a pulpy Noir Spider-Man nor even John Mulaney as the Looney Tunes inspired Spider-Ham; it's Shameik Moore and Jake Johnson. These two have don't just have impeccable chemistry, but both end up needing each other in more ways than one. This Peter Parker is just as in need of help becoming Spider-Man as Miles, and Johnson's tones, his delivery, and general performance convey that beautifully, similar with Moore, and his general awe, confusion, and passion for what he loves.
Lastly, the character designs in this are some of the best I've seen in a long time and the score by the amazing Daniel Pemberton is as fist pumping and awe inspiring as you were expecting if you're familiar with his work....
I'm just amazed at the fact that this movie exists, and what it does to push the medium forward with such care and passion is truly inspiring and I know for a fact this is going to make a lot of kids and Spidey fans very happy. I can't wait to see it again and I can't wait to see whatever the hell these people end up doing next.
Oh, and yes, you *NEED* to stay for the aftercredit scene....
Trust me. It's worth it.
