Guardians of the Galaxy (2014)

Guardians of the Galaxy (2014) redefined superhero cinema with its irreverent humor and cosmic adventure. Marvel's riskiest film at the time transformed obscure comics characters into beloved icons, following a ragtag team of misfits - Star-Lord, Gamora, Drax, Rocket, and Groot - on a galaxy-saving mission. Its perfect blend of heart, humor, and spectacular visuals, set to an iconic 70s soundtrack, proved superhero films could succeed without relying on established heroes. The film's emotional depth beneath its colorful surface and groundbreaking visual effects expanded the MCU's cosmic scope while maintaining universal appeal, making it one of Marvel's most original and rewatchable creations.
