Here's a review I did of this episode for another board, with my own interpretations:

- Imprint. Takashi Miike's... WOW. I have to start with this: even through this was produced by an american company and it's spoken in english, it is NOT an American work, its 100% (okay, 98%) Asian.
That is, everything in it follows oriental aesthetics: the rythm of the character's dialogues, the combination of beautiful backgrounds and raw human violence (without even the stilization that European Horror often employs), the perpetual coexistence of the supernatural and the "real", the horribly twisting storyline, the ending completely open to interpretation... everything about "Imprint" is Japanese Horror.
The story is deceptively simple at first and appears to be grounded, like many other MoH episodes, in gory violence (through here we have a long torture scene that would have made the Marquis de Sade proud and that is seriously the most disturbing thing I've seen in this series so far), but just as things appear to be drawing towards a logical conclusion, the viewer is assaulted with a series of plot twists until we can no longer tell what really happened.

...By the end, I guess there could be at least three explanations of what happened:

***MAJOR SPOILERS****

1. The woman with blue hair is yet another of those kami (supernatural beings) that often plague japanese horror tales and that can manipulate their victim's perception of reality. She has taken prey of the reporter and has completely destroyed his sense of reality.

2. The reporter did indeed kill his sister back in USA and now he has killed Komomo. He was insane from the get-go.

3. The reporter is dead from the start and is now trapped in Jigoku, the Budhist version of Hell --Large bodies of water are through to be the gateway to the oriental otherworld, and the episode starts with him and other "lost souls" crossing a lake infested with petrified corpses...

***SPOILER END****

...Or maybe none of them are entirely correct.

This, frankly, is what I admire most about Oriental fiction in general, that unlike most of its occidental counterparts, rarely offers clear-cut conclusions, and the viewers must always figure things out for themselves.

In sort, Great episode, I was pleasantly surprised by it.

I hope that helps some.
