An interesting study in "how to do horror by the numbers."
1. Hint at a horror (legends, rumors etc.). Main character is, of course, skeptical.
2. Horror appears. Main character does not believe senses.
3. Horror chases Main character.
4. Main character escapes (death of secondary character(s) optional).
5. No one believes Main Character's story.
6. Just when everything seems safe, Horror makes one final appearance.
All that would be alright, but I did not think this story was fun enough to get away with its formulaic plot.
