Opinions on "The Tales of Beedle the Bard" by J.K. Rowling?

I first saw the book in Target and it looked as big as the Junie B. Jones books. Then I went to Barnes and Noble to buy one of the Twilight books and I saw the book again so I figured I might buy it for a half hour's worth of reading. It was the crappiest thing I have ever read. There were five stories that were each about five pages long. And the commentary by "Albus Dumbledore"? What the **** was that?! They were each almost fifteen pages long and they weren't even remotely comical! All in all, a complete dissappointment. Any other opinions?
