As many of you would have come to expect by now (if you can remember these type posts from the past), I voted BWP.
This poll quite fascinatingly pretty much exactly represents the inverse of my feelings on which album is the best, relative to each other - as it is right now, that is, being:
Orchid 13 33.33%
Morningrise 4 10.26%
My Arms, Your Hearse 3 7.69%
Still Life 5 12.82%
Blackwater Park 14 35.90%
For me, the middle three are far and away better than the outer two for their strong compositions, flow, style, and my interpretive sense of emotion. I completely concur with X's review of Orchid, with the exception that I simply feel that much stronger about the middle three. I can also concur with Lina's points on "disjointedness" - the concept albums (and the 5 track Morningrise) appeal to me in their sense of wholeness, and the outer two albums are certainly more lacking of that. When it comes right down to it, though, I think I just like the compositions on the middle three more, and they have fewer areas I find myself critical of (finger once again pointing at middle of Dirge for November).
(Actually, a more accurate representation would have Orchid at about 8, not 13, but anyways...)
Interestingly enough, I find myself unable to stay awake through Morningrise and Orchid nowadays when listening to in bed, but don't seem to fall asleep to the latter three. Production sound, I wonder? It can't simply be familiarity...
