So the million dollar question and my biggest confusion is this: who was the mysterious guy/killer he was chasing—during the first few minutes of the film-- and hacked him? I get that it was “him” all along watching himself and how he is the responsible person for the deaths. Like sort of a time travel, or maybe a thought bubble in motion, but it can’t be a Kang Min vs. Kang Min encounter because that would be too absurd, how can that be possible. He can see himself from afar, yes, but to actually lay hand on his person is another story. Or the person who inflicted his wounds was his police friend? Or maybe that person was the mysterious caller who tipped him of his lover’s affair?
When is Min hanging out with Su-in? I assumed she was his "guiding light" for the fourteen days he was in a coma, leading him to understand what he had done and that he had died. But But But, he's with her before he does the killings. And he's not bandaged up. I know there's an explanation for this but it's the part that befuddles me.
I don't have any confident answers. No matter how you slice it, there are continuity problems, both in the time loops and in the mysterious figures. I personally believe that all the guys in the forest watching each other are "Min." The guy calling and sending film is Min. Since, apparently, most if not all of this is his mind playing out guilt scenarios during 14 days of coma (after, apparently, hacking his boss and girlfriend up) the fact that "observer/follower" Min somehow lost his bandages seems like a forgivable mental discontinuity.
I, too, entertained the thought that Min was dead and that Su-in was his guiding angel. (
Jacob's Ladder?) The ER scene could be re-interpreted that he died. And when Su-in was telling him the story of the spiders, she specifically said "
they don't know they are dead" b/c their memories disappear. (
Sixth Sense?). And add a blue(ish) key that surprisingly turns up to a befuddled holder... (
Mulholland Dr.?)
But I'm not happy with that interpretation, as at least
some of the timeline and discussions with his cop friend had to be grounded in real-time; real-life, right? I can get on board with "mind coming to grips with horror and guilt during coma," though.
Interestingly, the movie that
Spider Forest quite reminds me of, somewhat, is
Angel Heart.
