- Memento's backwards narrative can feel somewhat gimmicky. but it forces us to live through Leonard's perception of the world, seeing a scene with no knowledge of the (usually critical) events that lead up to it.
- One thing that lends credence to the theory that Teddy is telling the truth about Leonard's wife surviving the attack and it was Leonard who killed her is that even in the heat of their argument at the end, Teddy always specifically says that the assailant raped Leonard's wife, never including that he killed her.
- At the end of the movie, you can be left with two conclusions: that Teddy was lying to Leonard, or that he was telling the truth. Which means that either Teddy is a Manipulative Bastard, or that Leonard is taking advantage of himself just as much as the rest of the cast. Neither interpretation is especially happy, but which one is worse?
