I've also always been confused by the apathy toward Amnesiac. Many of my favorite Radiohead songs are on it and it seemed just as interesting, if not more, than Kid A.
I've always found that I love the individual songs on Amnesiac as songs, but as an album, it's not as cohesive or gorgeous as Kid A. I can't back that up with anything but subjective perspective, but it's my feeling.
