I love it.
Knew it'd be an instant classic for me when I first heard it, and I've never gone back on that. While Dramatic Turn was an exercise in delivering the most clasically Dream Theater album they could produce, ironically enough the self-titled album went a bit more outside the box, exploring a wider range of sounds, and giving more of a feeling of the band moving forward into new territory.
DT12 isn't exactly the band's most different album(No-where near as much of a lateral move as Astonishing would be, for instance), but it was a breath of fresh air after the somewhat samey(Though still really awesome for what it was) Dramatic Turn album, and honestly, I really like every song on the album. Wouldn't skip a single track, and would be happy to hear any of them come up on shuffle, or just to listen to the whole album.
Really, my only complaint with DT12 is the fact the CD release is too compressed, muddy, and loud. But even through this poor mastering, the songwriting and performances shine through, and I'm very happy with it. Self-titling it was a bold move, but made a statement I can totally understand and get behind.
