Are FIVE Villains in Spider-Man: Homecoming too many?

Batman Begins had 3 or so villains, no one minded there.

It's not the amount of villains, it's how they're implemented into the story. The Shockers are clearly just going to be thug minions of Vulture, and we don't know if Scorpion is there as a villain or if he's just Gargan. He might be set-up for another movie.

SM3's problems was that they didn't know how to implement the 3 villains properly.
