A job well done... or not

I just read this review in the Onion of the apparently ridiculously long-awaited new album by Guns N'Roses.

I'm not sure why I started reading it, because I have never heard an old album by this group and have no interest in the new one. But I kept reading to the end, at which point, I wanted to run right out and buy - no, not the album, even though it was quite a good review. Instead, I couldn't believe that anyone could be such a good writer that he could get me to read 1700 words (I counted) about the new Guns N' Roses album, so I wanted to run out and buy one of this guy's books.

There is some kind of important lesson about writing here, but I can't figure out what it is, because I can't decide: Does this mean he is doing a good job as a reviewer or a terrible one?
