Just like anything that has ever existed, I'm sure people will dislike this album and say it's not DT enough, heavy enough, SFAM enough, "early-DT" enough, Portnoy enough, and the like, but if you listen to a progressive band not expecting them to change their style - especially 30 years into their career - you might want to stay away from this album.
Of course, I haven't heard it, but I have read that it will be very melodic and, judging by the apparent prominence of acoustic guitar and piano, "soft", it will be different. I'm sure it will have heavy parts (especially judging by the trailer), but I am personally ecstatic for this album. It sounds grand, and I've always been fond of more soft, melodic songs than quick shredding and Rudess freaking out on keyboard. That's not to say I don't appreciate a killer riff here and there - Beyond This Life was a highlight on SFAM.
With that said though, the trailer is hysterical. I love concept albums and storytelling through music, and TA concept sounds very intriguing, but oh man, some of those animations were laughable. My hype is still in full force though, and I can't wait to sit down January 29 to listen to this album.
