Well, yeah.
Of course the album isn't exactly subtle in it's expressed emotions. Considering 7 of the singers are supposed to be personifications of human emotions, I wouldn't expect them to be subtle. It would be different if these were fearful characters, rather than one's fear in itself, doing the singing. And in that I think most of the singers are on the mark.
While I realize that this approach might not suit everybody, it hit a chord with me, it has kind of this theatrical approach to the album. It's kind of a Metal Musical in fact,... Maybe I'm influenced by the fact a dear friend of mine is heavily involved in musicals, but I love it.
