Yeah, it is a bit high. But it's his review and that's how he feels about it. That doesn't make him wrong. It means your opinion differs from his. (This is just my opinion.)
You're supposed to look at the album you're reviewing objectively, so while reviewers tilt can be as high as he wants it to be since that's his personal opinion, everything else is supposed to be graded objectively. Look at pop punk bands that were doing the same thing around the time this album came out, except much better. This album does not deserve a score in the 90's in any way.
