TO GET - The director's cut doesn't have the opening spoiler narration.
A man, waking with no memories and thought to be a serial killer, flees his pursuers and not only learns he isn't who they think he is, but they aren't who they think they are either.
A fantastic movie.. at no point was I bored. To me, this one of the foundations of a particular movie style. It isn't that it's whatever kind of "neo-noir" but that it tells a tale about reality itself.
