Eternal Sunshine of the Spotless Mind ★★★★★

One of the most heartbreaking movies that can still be classified as a comedy. It's the story of a bad breakup, and an invention that erases every memory of a person, and one patient's journey trying to reverse the effects of the operation while inside it. It has some of the most beautiful visuals in film history and the ending scene in the beach house... wow. By far Jim Carrey's best role.
