Vulture was able to carry a movie because they essentially turned him into Norman Osborn.
I completely disagree with Vulture being Norman Osborn. Their motivations and general ideas could not have been more different. Norman controls his own giant organization in the hopes of being able to create a super serum that drives him mad. Vulture is a guy who was completely dicked over in life and said that he's going to take things into his own hands and get revenge on them by stealing all the tech to get the payday that he should've had. Personality-wise, Osborn is just a rich, confident business man. Vulture is a gruff family man with motivations beyond just having an amazing company and then going crazy and murdering people. Hell, he doesn't even hold a vendetta against Spider-Man at all. He just goes "Yo Peter, you need to back off or else I'll have to hurt you." And that's all. Simple and to the point. Were it Osborn, he actively would've went out of his way to kill Peter. And even after being thwarted, he has enough respect for Peter saving his life that he refuses to give him up. Not like Osborn in the slightest. ---
