"Not bad - bad also not really great. Granted, I've only listened to the album a few times - but I very much doubt that it will grow considerably on me over time, because the songwriting leaves me unimpressed.
I can't help thinking that Portnoy's absence has moved Dream Theater closer to "normalty" - they still have an "out there" composer (Rudess), but I really miss Portnoy's over the top crazyness and his desire to incorporate an eclectic range of influences (ranging from 70s Prog Rock to modern Art Rock like Muse and Extreme Metal like Opeth) into the music.
On this album the most obvious influence is Rush - indeed, at one time the lyrics mention "restless angels" and I couldn't help thinking of Rush's recent album (Clockwork Angels), since the music was also a good match.
Having said all that, the album is very well made and nice to listen to, all the other DT ingredients are there ... even LaBrie's vocals are much better than usual. Alas, the inspiration for great tunes is sorely missed. I really prefer Haken's 2013 album "The Mountain" - no THAT's inspired songwriting, and musically easily on par with Dream Theater."
