The Marvel Cinematic Universe timeline can get a bit tangled, but yeah, 'Avengers: Infinity War' is the next big team-up after 'Age of Ultron'. There are a couple of movies in between, though—'Captain America: Civil War' feels almost like an Avengers film with how much the roster clashes, and 'Thor: Ragnarok' sets up some key stuff for 'Infinity War'. It's wild how 'Age of Ultron' planted seeds that didn't fully bloom until Thanos showed up. Wanda's powers, Vision's stone, even Tony's nightmares about alien invasions—it all loops back.
What I love is how 'Infinity War' pays off threads from like a dozen movies. The Russo brothers somehow made a crossover event feel personal, especially for characters like Thor and Tony. That said, if you're binging the MCU, don't skip the solo films between 'Ultron' and 'Infinity War'. 'Black Panther' and 'Doctor Strange' introduce crucial elements, and even 'Spider-Man: Homecoming' adds texture to Tony's arc. The way everything dovetails is part of the magic—or the madness, depending on how deep you wanna go!
