They wanted to find an ingenious way to put all the Spider-Mans together... and they DIDN'T.

And why would they bother?! What does this accomplish that's so special? They obviously wracked their writers brains to the point of mediocrity to settle for this very cheap excuse to combine all the different movie Spider-Mans in one movie apparently for the sake of novelty, because the story serves absolutely no purpose, AND it just resets everything for Tom Holland's Spider-Man, which makes the previous 2 films really inconsequential, on top of creating a dilemma for any future possibilities of featuring all of those villains we've now just seen, which technically Tom Holland could have had versions of in his own franchise. This film was a waste of time, and one of the very worst in the entire Marvel series. In my opinion, everyone involved in coming up with this concept should be fired.
