Thank you. Reminding me of those characters convinces me even more that the fall from grace is the far more compelling story.
Which sounds like a weak villain motivation for a film like Spider-man.
In an animated movie made for all ages. I expect Spiderman movie villains aimed at a more mature audience to have more depth with a strong character arc.
IOW, you just dislike the idea in general. No need to hide behind 'wouldn't alternative x be more original'.
The difference to most of those characters would be that they were just relatively normal people.
An actual superhero turning bad I haven‘t seen so often.
Mordo clearly qualifies, as does Batman. Also Jean Grey (soon to be twice over). Pyro in X2. Magneto in First Class. Really, half the cast of First Class. Sinestro. If we're including MCU tv, Davos from IF and Elektra from DD.
