It is done from a metalhead point of view, and at that it succeeds in giving a good idea for the most open minded of metalheads. See my review for my vision of the album, which is much better in my opinion
However, again this could be seen as an example of projecting one's conception of a band's creative path between albums as the truth. Just in this case, it's positive
Overall it's well-written though, and as alex said, good ideas and open-minded.
Plus digitalmetal.com were really awesome and accomodating with that whole Dark Symphonies press release fiasco last year, so they get high marks in my book.
