Query: Weakest of the series...

This is a good book, unfortunately it falls below the high standards set in the previous books. For two reasons.1) The art. Jeff Smith's art is still good but in this volume it feels rushed. Characters and landscapes lack the attention to detail that Smith usually provides. If you don't believe me, just take a look at The Great Cow race and compare it to The Crown Of Horns. The art is noticeably not as good. In my opinion Smith peaked at The Dragonslayer and started paying less attention to detail from then on.2) The plot. It just doesn't make a lot of sense. It feels like Smith started the series without a clear idea of how to tie everything together in a climax and had to introduce all these mystical plot devices at the last moment, just to wrap it all together. It wasn't quite satisfying and a little too weird in parts.Still it's a good conclusion to an epic series that reaches greatness on many occasions. It just isn't up to the usual standards.
