If you're wondering if the bashing this movie got is deserved - it is. I try not to go down the rabbit hole explaining very little detail of why, though: you can find multiple videos on YouTube, that do that quite nicely. I will only say, that it's main problem is that it tries to be not just a super-hero movie, but a Spider-Man movie. If they dropped this ambition, it could have worked. Or at least it could have worked better: it still would be a b-movie, probably, but that would help manage people's expectations, at least.
I mean, there is practically no connection to Spider-Man besides Ben Parker (who is pointless here as a character), and spider-powers and spider-associations. While using spider-webs as analogy to or representation of fate, futures and precognitive powers can still work (since it's not unique to Spider-Verse, and is genuinely an interesting concept) everything else is just complete fluff. In fact, they do not really lean on web and threads metaphors and analogies that much even.
This movie could have worked outside of MCU if they dropped the villain (because he is just stupid, completely underdeveloped and useless) and instead focused on Cassandra fighting her new powers (which probably should have been gotten somehow differently or should have started way earlier) and accepting those powers after bonding and saving the 3 girls. The danger for the girls should have been some huge accident (maybe even a super-villain attack or just a cataclysmic event like a huge earthquake, tornado or whatever else). And there definitely should have been more bonding time with he girls so that Cassandra would have been motivated to save them not just for the heck of it. After saving them, she may even see their future where they get powers, that can be used as a peak at sequel.
But alas, I was not the writer for this movie, so what the got is at best a movie to watch in background, when you have nothing else. Because the moment you start to think about something or take notice of some bad dialogues the perspective of a passable movie just crumbles. I mean, Venom, at least, had an interesting character, and interesting interaction with symbiote. Completely not related to comics, but funny and fun to watch. There was also action. Like proper action. This one was just "meh".
