X2

Christopher Nolan's take on the Batman mythos offers a darker, more realistic tone in superhero movies. Batman Begins features in-depth character exploration and a moody atmosphere that viewers who appreciate the serious themes in X2 would enjoy.

Kicking off the Marvel Cinematic Universe, Iron Man is a film that, like X2, balances character and action, with a strong performance by Robert Downey Jr. anchoring the origins of an iconic superhero.

An all-star Marvel superhero team-up, The Avengers brings together individual heroes to combat a common threat. Those who liked the ensemble cast and high-stakes action of X2 will find this film's collaborative dynamic particularly thrilling.

Another sequel in a classic superhero franchise, Spider-Man 2 is hailed for its character development and action sequences. If you loved the blend of personal drama with superhero spectacle in X2, then this follow-up to Sam Raimi's Spider-Man will swing right into your favorites.

Mixing superhero thrills with political intrigue, The Winter Soldier dives into the complexity of its hero's adjustment to the modern world, much like X2 delves into deeper themes behind its spectacle. It's a must-watch for fans seeking a more mature take on the genre.
