Batman has become a tentpole character for both the comic book medium and the movies that they've inspired. Perhaps more than any other hero, save for Superman or Spider-Man, Batman has become a fixture in the cinematic landscape, with more of his movies being transformative hits than straight-up misses. Tim Burton's Batman was the first to shine a light on the darker, more brooding aspect of the character, while Christopher Nolan's Dark Knight trilogy offered a more grounded take that emphasized the idea of Batman rather than Bruce Wayne. But in the decades of Batman movies that helped make the character timeless, it was Joel Schumacher's movies that reinstated a colorful tone to the character, even if its effectiveness has been up for debate.
