I don't even know what's considered average or above average or bad for DT. But simply put, the album is better than the worst but worse than the best, so I put average.
I think you would just determine that by how you rank it in the discography... Something like:
The Best = #1
Above Average = #2-5
Average = #6-7
Below Average = #8-11
The Worst = #12
I would say, at this point, above average. Which really surprises me. I didn't know from the start what to make of this album... I'm a definite Portnoy fan on the production, drumming and vocal fronts. But I must admit that the two non-Portnoy albums are certainly above average. Maybe there are ways in which the band's songwriting improves without MP's presence. Hate to say it, because I love the guy, but ADTOE and DT12 are really good.
It took me a long time to get there. Perhaps it was because it was the first DT album whose release I awaited, and it didn't exactly meet my expectations at first, particularly with regard to sound quality. Over time, though, it grew on me, and when I returned to it a few weeks ago after having not listened to it for probably well over six months, it really jumped in my rankings. It's a solid disc all the way through, and it probably helps that it was the soundtrack to the beginning of one of the best years so far of my life. So, yeah, above average, at least at this time.
