I'm not so sure that the musical as a genre of movie ever really died. But like anything else in Hollywood they go through cycles. There will be a truly great, award winning, lots of money making movie; then the copycats will start making movies that are worse and worse until the idea goes around that this genre gets a bad reputation.But that's a nit. Mr. Muir has done a great job talking about musicals from the 1920's to now. About a quarter of the book is a general history to get us up to through the 1980's. The remainder is broken down into decades. From the 80's and into the early 90's musicals languished. Not a solid hit among the bunch. Then came 1996. Madonna did 'Evita.' Then came 'Chicago' with a bunch of Oscars. Finally the book ends in 2004 with 'The Phantom of the Opera.'The musical has changed over time and the book talks about these changes in a literate and understanding manner. Very interesting reading from a very knowledgable author.
