Query: I was disappointed

I love haiku. Well-written haiku, however. Many of the haiku in this book seem to be sentences divided into three lines. That isn't haiku. If one observes the 5-7-5 or a total of 17 syllables, many haiku in this book fall short. In some instances, the last line (supposed to be 5 syllables) was 10 syllables! There were some nuggets here and there but, all in all, I was disappointed in this book.
