The following ruminations on Memento should probably not be read in advance of seeing the film itself.

I completely disagree that the film only makes "some rather simplistic points about memory itself." First off, I think those points are far from simplistic, especially in re questions of to what extent Leonard creates his own memories. But I think Leonard faces a very interesting moral moment at the end of the movie (or the beginning of the movie's timeline): he discovers he has been a golem, a machine carrying out another man's murderous desires, and he finds a way to end that amoral life. I think a golem's-eye-view is a provocative notion, myself.
