Let me elaborate on my previous statement (cuz that's what I love doing).
Deftones get old quickly for several reasons. First of all, there's only so much of Chino I can stand. His voice can really wear on the nerves. Also, the albums are so lack luster. It's like you want something out of these guys but they fail to deliver in a full CD. In every album, they have a couple good songs, but the overall albums are too dissatisfying. For example, the first album had 7 Words - which rocks. The rest of the album was just annoying though. It's basically the same story for the other albums.
Mostly, their style bugs me and I wish they would put some more well instrumentated aggressive stuff out.
