I found this really interesting article on how super villains have changed over the years, essentially stating that the hero's arch enemy used to appear in the first film (Superman vs Lex Luthor, Batman vs the Joker, Spider-Man vs Green Goblin) but now seems to appear in the second film (Avengers vs Ultron, Batman vs the Joker, Thor vs Loki). Do you guys think eventually the ultimate bad guy will be saved for the final film in the trilogy?
I also wondered if you guys think it's better to have one villain throughout a series such as Loki, such as Magneto, or if it's better to have a different/multiple villains in each film, essentially being self-contained movies rather than obvious sequels?
