I don't know, I have a soft spot for BC&SL. It has its flaws, but it also has its charms. Same can be said for SC, except I think THAT is the album where they flipped the script and took a detour, never to find their way back to the main route except on the follow-up. The last two songs on BC&SL are some of the best songs musically that they've put out since Octavarium, or ever.
Once Portnoy left, the best moments are still lacking something, seem undercooked, such as on ADTOE or DoT, retreading old ground, such as on ADTOE, DT12, or DoT, or taking a known risk with making the Aladdin & The Return of Jafar's Beauty & The Beast soundtrack, I mean, The Astonishing.
