People like me do only post our opinions of course, but I genuinely doubt Keaton's vulture would be called the "best villain of the MCU so far" if he had feathery arms and a green onesie on.What a load of nonsense sense! Of course a classic Flash would work! It would look better than this leather garbage looking Flash. It would work just like Christopher Reeves Superman, every Spiderman did. Comic Vulture would work a lot better than that mechanical monstrosity Keaton is wearing. Why do people like you post wrong headed points like it's fact?
And again, in my opinion of course, I just don't think that the flash, wearing a skintight red onesie, would really work with the semi realistic tone they're going for with the movies.
