I see what you mean. Though I do feel some of the stuff on the second half.
Album kinda just chugs along with a unguided sense of melancholy. Like where are the tempo changes? The shouting? The pain? It's all sort of complacent in hopes the listener will thrust a certain mood onto the album and just "feel it," which many will probably end up doing. But in the end as a whole it fails to move me, sweep me off my feet like Funeral. There are parts that come close or do this, but they are few and far between for a sprawling 16 song album.
I feel Funeral mastered a feeling, the orchestral build up in most songs introduced melancholy and developed it into something further, pain; regret; desperation; inspiration; warmth; and love.
Neon Bible kinda took that large urgent sound and became an album on the verge of cliche or parody, so filled with angst and bombast and kinda lost some of the innocent sincerity Funeral had.
I think they may have just tried parring back that dynamic approach but kept similar Arcade Fire themes for The Suburbs. Unfortunately to me it feels just a little empty, and again, cliched. They kinda mastered these themes on Funeral with a greater dynamic, and trying to do a similar thing with less range, but more length kinda makes the album feel dry lots of the time.
But I've only listened once, and I'm sure theres room for this to grow. I'm sure it's a good album, but I'm also sure it's not a particularly great one.
