When Sony announced that they would be doing an animated Spider-Man movie after giving the live-action rights to Marvel, I was a bit confused. There wasn’t any need to make an animated version of the character, especially when all eyes would be on the Spider-Man in the MCU. But when it was announced that the movie would be focused on Miles Morales, the Spider-Man of the Ultimate Universe, it all finally clicked. Miles Morales is popular, but not as popular as Peter Parker. Giving him a smaller stage to shine on is exactly what the character needs.
