I caught this in High School and it instantly took me as an eerie Alfred Hitchcock show that did an outstanding job of feeding on pure paranoia.

It was unsettling, it was scary, and at the time it seemed as realistic as it could be for an anime movie.

As I rode through it, I started doubting what was real and what wasn't and that is a hallmark of a great movie, that ability to keep the viewer on their toes.
