It's a good song, some great parts to it but not fondof the female screaming (it wasn't too bad to ruin the song, thankfully), or the outro. I don't like the children being used to try and be creepy thing, I've never found it to work. I don't know why I get more excited when I hear that an album is a concept album with a story though, because it's usually the conceptual or story parts I don't like, like interludes, dialogue, sections without proper music etc. Concept albums of that type always seem to produce great songs and music apart from that stuff though (e.g. Seventh Wonder Mercy Falls, SFAM etc.).
