Rank the trilogy's three main demons from scariest to least scariest
Red Faced Demon
Old Lady/Man Demon (forgot the name)
The demon that can't breathe
For me I'd probably say Red Face was the least scary. When you first see the face it pretty much looks like the scariest thing you have ever seen. However, the more you see it, the quicker you realize Red Face is more bada$$ than anything else. His chase scene makes him seem ever cooler. Plus he's got a lair. I think of him like I do Freddy Kruger, yeah it's scary, but it seems to have too much of that human personality for me.
In the middle I would put non breathing man. Honestly, for a main villain, he was disappointing. He seemed pretty generic to me. I also don't think he himself is really that scary. Most of what he did to the girl was scarier than HE actually is. He looked like a zombie more than a demon if anything.
I'd say the old man/woman was definitely the scariest. The smile, the big dress, the shawl, the teeth, she/he is just seriously creepy. I think that demon takes the cake of scariest thing in the Further that we have seen.
