A real drummer is credited for the drums on the record, so I'm wondering what the hell went wrong for the end product to sound so digital and robotic. Was everything sample-replaced? Digital triggers? No idea, but it sounds awful.
As for Sonata: it's just a demo. There are some cool ideas in there, but it needed some serious editing, as in cut half the song because what we have is not enough to fill 10 minutes of music. The lyrics had the potential for an interesting story, but the music doesn't take advantage of that. There is no evolution.
Hell, time for a controversial take: The Angel And The Gambler, another song that is commonly seen as being too long and that shouldn't have been ten minutes long, has more variation and dynamics, and evolves more throughout its timespan than Sonata does.
