Just look at the 2007 ones Spider man 3 and from 2014 The Amazing Spider-Man 2; the former featured Sandman, New Goblin, and Venom, while the latter used Electro, Green Goblin and Rhino. This isn’t to say that all of these villains were misrepresented (I like Thomas Haden Church’s comprehensive portrayal of Sandman), but there’s no denying that one of the reasons those particular Spider-Man movies didn’t go so well received like the others. It was due to a mass of villains. Now granted, Spider-Man: Homecoming He managed to fit in with many villains, including two versions of Shocker and a non-Scorpionized Mac Gargan, but it was only Michael Keaton’s Vulture who took on the role of the main villain. The same goes for Spider-Man: Far From Home, which adapted various Spider-Man villains as Elementals, but Mysterio was the man running the show.
