Vulture isn't one of my favorite villains, but I've noticed various people on the internet are being so quick to dismiss him and calling him lame which I think is pretty short sighted and are really underestimating the potential he could have. Especially if they get a great actor to play him. I feel like with a bit of work they can make him a brilliant villain. An bitter scientist who got discarded for being old and mocked for his looks. They should portray him as such. Maybe Toomes could be the creator of the flight gizmo, and the government giving him no credit could be part of his resentment towards everyone.
I also don't understand how people can think that Vulture is lame but Falcon isn't, when they would be quite similar. Falcon's aerial scenes in TWS were among the highlights of the film. But we haven't seen an evil version of that using far deadlier force, which is what Vulture would do, perhaps having a more advanced, sophisticated version that he has invented.
