First Time Watching
The clip was a bit odd, but that was the expected effect. However, the fear hole does not look scary or "fearing." I think I can look better if the vortex is like the Diablo 2's Gate of Hell or the whalling wall from the Simpsons (Treehouse of Horror XII) because I feel that I (like in Doom 3) to go into the portal and kill some monsters. To truly be a fear hole, there should be a lack of desire of entering it.
Fear is based on 4 items I can currently think of. They mess with 3 of them.
Physical: ex. Resident Evil; Mostly pain and death
Mental: ex. Silent Hill; Is this real or not; evil or not
Spiritual: ex. Exocist; control
with duration (time) ex SAW series. This is why people remove their eyebrows (pain) without too much though because of the small of pain. However, if it lasted for all eternity, they would think twice about it.
On the lighter side, I noticed most of "humaniods" have addons or upgrades like saws and other werid items. I think, unless Sailor Jupiter(the girl at the very end) is from the Fear Hole not one of the Professor Scarecrow's people, she used to be normal but the professor has installed a very bad voicebox filter in her throat, two types of contacts in her eyes, and plastic vampire teeth from those $1 toy vending machines. I am sure if those were removed, she would ok.
