Much like Leonard's disjointed sense of memory, the film's plot manifests itself in bits and pieces of the main character's experiences. Such a plotline is rather hard to characterize. It doesn't really take place in a straightforward and linear fashion, but neither is it nonlinear; rather, the movie shows us every incident in reverse order. Viewers are invited to see for themselves the bizarre things Leonard will never remember he did, let alone understand.
Christopher Nolan writes and directs this masterpiece with true vision. A little tedious to some but gripping to those who enjoy a good psychological thriller, Memento may be the most novel film in said genre ever conceived.
