I understand. Honestly, when I got into DT, I never really considered them totally original, but I loved the way they incorporated many influences, and did so with such a high degree of musicianship.
I could never get through a Yes album, or a King Crimson album, but I love how they take that influence and present it in a way that I can really appreciate.
Personally, I though ADTOE was fresh. Songs like FFH and BTS were the types of songs I was looking for. I don't need my metal from DT. I thought DT12 was the safe album, not ADTOE. I feel like those albums were released in reverse order.
With TA, it can be a bit long and clunky at times, but it's quite an album.
