Its got some amazing parts (Praise the Lowered, Stand, Juular, Masturbator, Deconstruction, Poltergeist), but I don't like Pandemic at all, and the first half of Planet of the Apes has really awkward vocal melodies and it really takes me out of the song. Sumeria is just eh overall (despite Duplantier's awesomeness).
Compared to the amazing releases last year and the other perfect DTP albums, I just don't find it THAT amazing, though I respect it for all its heavy, melodic, crushing insanity.
