Except Dr Strange, he's acting in a really dumb manner in this film most of the time considering how overpowered he is and how he should be acting/responding to Peter and certain scenarios. Oh, and you have to forget the TVA exists.
When it comes to the whole GED, I think we're under the assumption that everything is gone, so he has to rely only on himself. Part of the issue is how does this mechanically work. Does he just 'exist' with everything wiped out? Does the spell really just shift him into a different universe (a la Steins;Gate timeline hopping where Peter is the only one that knows anything happened) where Peter is just isolated from everyone? It's certainly implied it's not just face blindness or memory wipes, because there are hints that there's way more going on. It kind of ties into how the original spell is meant to work and what actually went wrong with it, as it's not defined... so they want you to just accept that's the way things are. I personally write it off in my head that the spell actually moved his consciousness into a different universe, and that's the way it was intended to work... and Dr. Strange and Co. don't know the true nature of the spell because "we know frighteningly little about the multiverse" and such. It's a cope out, don't get me wrong, as it's left so vague and wishy-washy in terms of mechanics.
This also raises the issue of Mysterio, as we don't know the exact mechanics beyond what the movie chars think they know... and I'd like to think that they're clueless or misunderstanding as to what's really going on in terms of the botched spell (or even the intact one), as it makes more sense in that regard. From what we can observe, it's absolutely possible that some form of Mysterio could've popped up. Heck, there could've been a universe where he was a legit good guy and thrown Spider-Man for a loop, leading to many different character development avenues. However, I think the film's fine as it is when it comes to who all pops up, because it absolutely elevates all the older Spider-Man films or helps address some issues with them.
Overall, in terms of plot and mechanics, I think the film's around a 5 out of 10... all the time/universe mechanics don't damage it nearly as much as End Game or Loki, as removing those elements from this Spider-Man film still gives you something pretty solid. In terms of character development, it knocks it out of the park... I'd even go so far as a 8 or 9 out of 10 in this department, with Dr. Strange being the big reason for why it's not scoring higher. In terms of entertainment value, it's not really surprising that this film is popular, as it's not spitting in people's faces while respecting past and present franchises while elevating them all and tying up loose ends from all the films. This film is a good example of how to do fan service correctly. It's not perfect, but it's certainly the best Marvel film in a long while.
