IMO it's great how Symphony X has always evolved a little into a new direction with each album. That's why The Odyssey sounds fresh to me. And about that journey feel, I think The Odyssey is the greatest journey song ever. And I don't understand how you can call songs like Awaknings, Accolade II or King of Terrors generic.
Still I hear similiar comments about The Odyssey once in a while. A lot more people have liked it tho and I'm part of them.
And about the tiering of Sym X records, I think The Odyssey, V, TIO, TDWOT and DG are all very close to each other. I just don't know which one is the best, maybe Divine Wings... Or The Odyssey... On the other hand V is amazing too. Propably one of those, but DG and TIO aren't far behind. Self titled isn't quite as good as the rest tho (as many know).
