I know vulture is going to be the main villain with a few other guys as the b villains but I would have loved had they gone with Clash as the homecoming villain. I loved him in the .1's marvel ran last year and I'm loving him in the Civil War II ASM comics running now, and I think he'd bring a visually interesting costume and power to the big screen. I mean sound waves basically would negate spidey sense and would give a mostly inexperienced Peter a big challenge to overcome.
