I've loved it since my first listen of Falling Into Infinity. It was my first "older" DT album (before I had listened to Octavarium, SFAM and Train of Thought), and New Millenium was a negative first impression, and You Not Me felt ok. But when this one entered... I knew I'm going to love old DT just as much.
The combination of the calm first half and the heavy, Metallica-influenced second half is great. Btw, I've heard there's some "2005 version", where is it? Never heard it myself.
