I've heard that the people Sony hired to make it apparently pulled off some trickery to ensure that they had full control, and Sony couldn't change anything.An absolutely absurdly well put together film. Definitely among my favorite superhero movies, period.
I'm still in shock that Sony Pictures were the ones behind this. Spider-verse's contemporaries are Hotel Transylvania 3: Summer Vacation and The Star. The last time their movies were notable was when they released The Emoji Movie. Where the hell did this even come from?
If so, it proved an excellent decision.
