Scared me shitless.
I always get a huge scare out of The Grudge or The Ring-esque movies, and this one is definitely no different. The long introduction can actually be more appreciated when you realize that it builds up huge amounts of tension through the use of a dark undertone and deep, melancholy chords.
The beginning chase scene was great and caught me off guard, while the whole red-eyed girl thing was brilliantly executed. I even bothered to sit through all of the credits, and when it reached the end... well, I'm glad I watched them! I felt the animation went well with the movie, however it seemed a bit stiff at times. The graphics were drawn well and the dark, stale colors gave the movie an intensely eerie mood.
Overall, I loved the vibe the animation gave, as well as the constant build-up of tension and suspense. Excellent horror flick, great work!
