Iron Man
MCU REWATCHCrazy to look back and realize this is where it all began. Even after rewatching it multiple times throughout my life, it still holds up as one of the best comic book movies to date. This movie just has so much sauce, I feel like it gets better every rewatch. RDJ as Tony Stark remains the best comic book casting of all time, and I really don't think that level of perfect fit is going to be topped anytime soon.
