Only one slight flaw, if you can follow it.

Rating: 9/10 (17 September 2001)

A very neat movie, though it risks bewildering and annoying viewers who aren't good at piecing it together. Editing it into a less confusing chronology, though, while making it easier to watch, would spoil the fun of figuring it out. Watching it a second time, I was able to catch (one of?) its near subliminal tricks, which pretty neatly confirmed what I'd concluded by the end of the first viewing. There's a minor incorrect detail: insulin is never even occasionally injected into a vein. If I'm nit-picking, it's because otherwise I could find nothing to criticize. Unlike with nearly all psychodrama, recent or old, I couldn't find inaccuracies in Memento's depiction of neuropsychology, or anything else. It's clearly a masterwork.
