I'm not going to be that guy and say "it's not spooky enough," because if CC had this comic dripping with blood or wiggling like a worm, this would not be a dialogue font. It would be an effect or design font.
The variations on this font are subtle enough to imply that this voice is "different," but the font is every bit as readable as the other ones on this site. I only give it one less star because I can't think of too many occasions on which I would use it... Unless your main character is a fiery headed spirit of vengeance.
