Makes no sense. *spoiler warning*
This movie doesn't make a lot of sense and has many glaring errors. I just finished watching it for the first time after hearing so many good things about it on here.
1) It doesn't explain why that girl was a psycho killer. I know she said she hates all living things, but still....
2) I've heard of destructive behaviors before, but eating oneself is ridiculous.
3) Why would you perform your initial test of a drug on 3 people who have no clue that they're getting it or understand why they're feeling this way? What kind of scientist is that? I know he's only 17 but you don't have to have a Doctorate to understand ethics.
The only character that made any sense to me, other than the mother, was the girl who was sticking herself with stuff. Self mutilation occurs all the time, though not quite to that degree. Also, why did he try to hook up with his mom? None of this was ever explained.
I also had some problems with some general errors in the movie. One of the worst, in my opinion, is that the girl obsessed with food deep fried her hand and ate her finger, yet when she has that scene where she cuts parts off of her body her hand is miraculously intact. Same goes for Eiji. The girl slits his throat yet when he's laying on the ground he has some blood on him but they didn't even attempt a prosthetic for a fake slit throat. For the amount of arterial spray, he'd be spread wide open. Another thing that could be just a minor inconsistency is that the time on his video never matched up with the outside of his camera (the led display). I assume the part where he's videotaping that girl killing his mother is a dream sequence, but Eiji is holding the camera and they show the activity through the lens but the video isn't recording. These were just some of my gripes. I was just upset for wasting an hour and 20 minutes so I wanted to vent. If you have any answers, please let me know.
