When I first became a fan, around 2007, this was one of the weaker albums for me. As the years have gone by, I've come to appreciate it more and more. Yes, its less technical and less heavy, but it maintains the atmosphere they had in their old days and has some excellent, deep lyrics. Bar one or two songs, this album still has a lot of the "magic" and intrigue that is sadly missing from 90% of their post six degrees material, Imo (though I still enjoy them, of course). I would say its a better album that octavarium, sc, black clouds, s/t and astonishing.
I would probably place it 6th or 7th behind images, awake, scenes, six degrees, tot and adtoe. And while that seems low its just because of how brilliant those aforementioned albums are.
