I been saying for awhile about vulture be an inventor of the wing tech the govt took it from him and he wants tech back. And a way to tie to mcu and have a good connection. Then a way you can also add the second vulture as a ex member of falcon group.
That's not a bad start, but there needs to be an escalation that leads to a climax.
Also how should Vulture's quest for revenge be portrayed? Is it sympathetic, where he has a completely valid beef with the government that he takes a little too far or is it a totally selfish and petty revenge, that he has no problem having dozens of innocent people killed to feed his desire for vengeance? Is it somewhere in between, where Vulture has a legitimate gripe, but takes way too far that it becomes unsympathetic, with him having a disregard for human life? Also what kind of character would Vulture be in general, is he just a selfish psychopath or does he have loved ones he cares about?
I would still pair him up with a more physical villain and would focus on Vulture as more of a mastermind type character. Make him seem smart, rather then just saying he is smart and giving him some tech to show off and techno babel to spout, give him a plan that seems a bit epic.
But we've seen that five times in Spider-Man films and twelve times in Marvel films. I wouldn't mind seeing something different - prove that Marvel can draw from the comics with a different time of superhero/villain conflict.
Didn't we really see that in the last film, with the rather bland rivalry between Spidey and Electro? Frankly the personal romantic stuff was the only thing interesting in that film, the villains were total bores. Plus haven't we seen a lot of lame MCU villains like Malekith, shouldn't Spidey raise the bar in terms of villains. Frankly I think the trope with the generic villain who robs banks, the hero stops him, villain swears revenge because hero stops him from robbing banks, should either be reworked or retired. Its just not that interesting on its own, I don't care much for it in the comics, unless a writer can do something a bit more interesting with these types of villains. At least give some of these bank robbing villains some depth, like the way Captain Cold has loved ones he cares about and a code of ethics he subscribes to, this why I think Captain Cold is a way better villain then say Shocker.
I wouldn't want a DD season where DD stops bank robbers for a whole season, I think Spidey deserves better villains then that as well.
