Might be. I'm not a fan of classically-tinged music at all and find "The Fountain Of Lamneth" to be the worst longer-than-average song Rush have ever written. It drags like hell, most of the transitions are very rough, there's the cliché of the drum solo in mid-song and many of the main melodies seem very cheesy to me ("paaaaanacea, liquid grace"... ugh).
"The Necromancer" is much better in my opinion, mostly because it's more focused and its end actually feels like the finale of a story. Rush managed the same with "2112", "Cygnus X-1" (their best extended song in my opinion) and "Hemispheres" (which I've never been a big fan of to be honest), but the ending to "The Fountain..." always felt very anticlimatic and flat to me. Different strokes, I guess.
