I'm gonna put this in a separate post because it wouldn't fit with the first, but Across The Spiderverse was an electrifying movie that I think shouldn't be allowed to skirt by on reputation. The characters, soundtrack, and animation were all stellar. Each spider is visually distinctive, with callbacks any veteran Spidey fan will appreciate. I especially loved 2099, and while I may not be a great fan of the change to his story, I do like that they were willing to be original in a way that gives him personal investment to the new narrative.
That said, there are different concepts and practices that don't hold up in hindsight. I can't go into great details without spoilers, but the spider people feel both less than heroic and redundant in their purpose. They're meant to watch over the multiverse, but there's nothing uniquely spider about the problem where literally anyone else couldn't do the job. The feel like a more flamboyant TVA. Miles tries to alter the path of his reality by saving someone, which all the spiders are against, but Miles by nature of how he got his powers is inherently an alteration, so who's to say he'd make things worse? There's also the concern of damaging realities even though they've shown that damage can be treated, so what's the point? Is it because it's inconvenient? And then there's hard set events being required even though part of what made the first movie work was that anything could happen. It's a 6/10 for me.
