Joss Whedon's Avengers movies are destined to be the least like his other works because corporate interests prevent him from killing any of the main characters. Every Whedon creation is high on the body count among the central cast: Buffy the Vampire Slayer, Angel, and Firefly (along with its big-screen follow-up, Serenity) never shied away from making the kinds of changes that most other series would consider too drastic. Whedon's work is, largely, about how people learn to cope with tragedy, and how they come to understand that the only thing they can control in a traumatic situation is their own reaction. However, he's not able to make such sweeping changes within the Marvel universe, since the direction of the property is ultimately out of his hands. The first Avengers film wound up killing a supporting player only for that actor and character to be revived on the television spinoff Agents of S.H.I.E.L.D. a year later. Whedon's Avengers films, then, are bound to be the least connected to his other works simply because they're forbidden from exploring the emotional territory that Whedon's come to value most. Financially, they're his biggest marks on the entertainment world, but narratively, they're his least personal.
