Kwame Opam writing for The Verge:
I can't imagine a better person to give his 2 cents on Spider-Man's entry into the Marvel Cinematic Universe. I also love his views on who could make a great cinematic villain;
Mysterio had never even occurred to me as a potential cinematic villain, but Dan makes an excellent point [one that no-doubt is one of the many reasons why he's writing for Marvel in the first place]. Mysterio would be one of the biggest spectacles a villain could ever have on the silver screen.
Who knows, maybe someday.
