Query: Knock off

I am extremely disappointed by this book! Just as others have said in their reviews, this book is a horrible knock off of the original books. The Crockett Johnson books are very clever. These other ones are trite and unintelligent. My son couldn't care less for this one, but carries his collection of Crockett Johnson tales with him everywhere he goes.I just wonder how this author was able to get permissions to create this garbage with the "Harold and the Purple Crayon" name on it. Even if this book wasn't being compared to the originals, it would fall miserably short. Whose idea was it to bring a dog into the story??? Seriously stupid.
