This film centers on a man who employs tattoos, written reminders, and pictures to track down his wife’s murderer, all while struggling with memory loss. Christopher Nolan's initial work ("The Dark Knight", "Inception") is remarkably brilliant. The narrative begins at the story's conclusion, then jumps backward in brief intervals, preventing the audience from having any context for what's happening and mirroring the protagonist's disorientation. Even so, the finale—which actually marks the start—delivers a significant surprise, exposing a deeply disturbed mental state. A true masterpiece! -- DrNostromo.com
