1. Green Goblin
Amazing Spider-Man 2 (2014)
Hoo boy. Yeah, this is the worst.
It's the worst villain in any Marvel movie AND the worst adaptation of a Marvel comic book villain to screen. And it's a shame too. When I heard Dane DeHaan had been cast as Harry Osborn, I was excited. DeHaan convincingly plays a menacing villain with a tragic backstory in 2012's Chronicle and really seemed built for the part of Peter Parker's fallen friend.
But in execution, it is a mess and he is given nothing to work with. The script is baaaaaad and gives him mediocre motivation at best. His jump from "I am mad at Spider-Man" to "I am going to put on a Goblin Costume and fly around and murder Gwen Stacy" is flimsy at best. And oh lord that costume.
How is it possible that every Green Goblin costume is worse than the previous one? First we had the silly but effectively scary Power Rangers armor, then Harry's Sk8r Boi suit in Spider-Man 3, and this"¦ thing. I don't even know what to call it as a joke? An evil Keebler elf? A demon with Acne? Lord, it is bad.
