BC&SL was my first full-length DT album, but unfortunately time hasn't been kind to it. I rank it above Octavarium and SC, but I think it's like a combination of all the things that were wrong with DT before MP left:
-Overlong songs
Both ANTR and TBOT would've benefited a lot from being trimmed down. Ironically though, I have no problem with TCOT and it's the one song I keep coming back to on this album.
-Too much MP vocals
You already know which part I'm talking about
Shouting words like "KINDNESS!" in TSF is pretty silly as well.
-Subpar lyrics and vocal lines
I think everything about the quality of the lyrics has been said already, but a lot of the time they also convey a totally different mood from the music ("everyone survived, roar!"). Some songs have pretty uninteresting vocal melodies (especially AROP), and it's clear that an actual singer wasn't involved in writing them, as it feels like the vocals were added as an afterthought and a necessary evil.
-Forced heaviness
I am a metal fan who listens to way heavier music than DT, and I like a lot of DT's metal songs, but on this album the heaviness feels kind of contrived and unnatural compared to TOT and songs like The Glass Prison and The Mirror. It's the more melodic stuff like TCOT, Wither, Beautiful Agony and parts of TBOT where DT get to shine here.
-Lack of band feeling
JM is doubling JP most of the time, a lot of Jordan's keyboard work is buried in the mix and James is singing vocal melodies and lyrics that he had no input on - all of this gives an "another day in the office" feeling.
-Some of DT's worst solos and instrumental sections
AROP - 'nuff said.
