Endless Sacrifice is meh and the 2nd worst song on Train of Thought (And it only beats Vacant because really, Vacant is a prelude to Stream of Consciousness, which owns the crap out of Endless Sacrifice). I don't hate it, but the instrumental section just isn't very interesting, I get bored listening to it and want to skip to one of the better songs on the album.
I really enjoy the Metropolis instrumental, but I honestly prefer James vocal highlights in it over anything else.
As for old vs. new DT, I just think its a result of DT being comfortable with what they are doing, instead of being hungry, but Orbert covered that nicely.
