Well SFAM had Home and Finally Free, which even though they're not exactly epics, they're still above 10 minutes which I don't think we should complain about (if it's the same case for this album). What bothers me more are those less than 3 minute songs that lead directly into another, or they have empty space and sound effects. SFAM pulled it off by having a very emotional story that flowed perfectly, not to mention only Regression and Through My Words were the only intro songs. This story could surprise me, but by the looks of it, it seems more fantasy based which doesn't pull me in as much. Also, there's one thing when you have a small "intro song" or two to bridge the gap, but when it gets out of hand like Ayreon's "The Theory of Everything" or Linkin Park's "A Thousand Suns", I lose interest because the whole album might as well be condensed into like 6-8 songs.
I'll just have to see how the whole story/album plays out, I guess. Still remaining optimistic because it's Dream Theater.
