There’s just no way around it,.. what was created with “Into the Spider-verse” was going to be a massively difficult film to follow up. The sequel had little chance, with the original -Oscar award-winner. “Into the Spider-verse” did just that. It brought the audience into a new universe different from that of the Marvel Cinematic Universe (MCU).
A universe of a new Spider-man superhero in a world within their own universe, where due to a scientific experiment in multi-dimensional travel caused crashes between these Universes. Much like the occurrence in “Spider-man: No Way Home”.
