It’s hard to overstate the importance of 2008’s Iron Man. The film didn’t just launch the Marvel Cinematic Universe; it also established so much of what would make the MCU successful. In terms of style, tone, and even specific character arcs, Iron Man established a pattern that Marvel has largely adhered to over the course of the last decade. That’s not a criticism. The reality is, Marvel Studios are very good at taking aspects of that formula, and subtly reworking them to create something fresh, new, and original.
