This author has written several books about films, so I'm guessing he knows about film. Unfortunately, he knows virtually nothing about musicals, and so this book is full of errors of fact, misunderstandings, etc. He routinely gets song titles, plot points, and musical terms wrong throughout the book, and he doesn't seem to have any respect for musicals as an art form. On top of that, this guy thinks Meat Loaf wrote the score for "Rocky Horror" (Richard O'Brien did). He thinks "Hopelessly Devoted to You" is from the stage version of "Grease" (it's not). He confuses the lead character's name with the actor who played him in "Strictly Ballroom" and gets them both wrong (Mercurio is the ACTOR). That kind of thing is all over this book.There is some useful information here and there, but how can a reader trust that info when there are so many mistakes throughout the book?
