The horse puppets are very unique and interesting. It would be quite an experience to see the stage performance.However, the subject matter gives me pause. I read a book many years ago called "Jack" by Brian Carter which appears to be similar in theme to "War Horse". As you can imagine, a book about horses (and people) who were involved in World War I cannot help but touch on the grand scale of carnage they experienced. There's a very ugly side of war that can't be ignored. And when it involves animals being used as instruments of war, some of it can seem very cruel indeed.
