I don't get why people claim Fallen is their best.. To be honest I think it's weak when compared to the rest of their stuff.. Especially compared to The Open Door. There's so much more variety in the music, and everything feels more deliberate and structured. I don't really know how else to describe it. I still adore the Fallen, but it definitely feels more....thrown together. And in a way, that's part of what I love about it. It feels a lot freer and more fun than any of Ev's previous stuff, but there's something about the very thought out way The Open Door is that I just love. Everything from the production, to the variety in the instrumentation and orchestration, the vocals and the endless layers of backing vocals....hell, even the TRACK order feels really considered and deliberate. Amy's voice and piano were the center of the songs and now, listening to the three albums the band released so far (with the new members and all) i still think that those piano/Amy's voice oriented songs with a bunch of creepy sounds and the big choir are the type of songs Evanescence does best.
Although the heavy parts were not really memorable, the whole point of the album to me was exactly that: creating an album centered in Amy's voice, piano, weird electronic sounds, a big choir and then the rock part was a sort of accompaniment, rather than the center of attention. And that worked well for me, cause TOD has this nice balance between Amy's experimentation both music and vocals-wise (which Fallen and the new album sort of lack) and the rest of the band's rock vibe, without overwhelming the former aspect of their music, that to me is the most interesting one. It's just such a wonderful album and i think it's often overlooked because it is much darker and less commercial.
