Anyway I hated it. It was about the peak or right after of nu-metal and it seemed pretty damn nu-metal; I thought it was overlong and "Third Eye" was as much a boring endless closer as "The End". I listened to it again maybe five years ago and liked it somewhat more, but why the band was compared to the Crimson is puzzling. They seem to be one of the influences on nu-metal, like Korn or RATM, kind of a more ambitious Filter.
Yes, I've heard Opiate as well, so I'm not hanging my opinion on exactly one release.
The cover to Ænima is cool.
"Hooker with a Penis" is a fun song.
