Query: Good opera

The title says, "The Musical"; but it's not just a musical, it's opera. Besides the songs, much of the dialogue is sung.There are many changes from the book to suit the opera format. These changes are fine, and the songs are great. Kelsey Grammer is a bit more over-the-top than most Scrooges; annoying, in fact, having a couple of minor physical infirmities (squinty eyes and a stooped posture) that disappear along with his bad attitude.If you don't like opera, this version is not for you. But if you do, it probably has the best musical numbers (some of them danced) of all the musical versions: better than the Albert Finney, Frederic March, and Muppet versions, right up there with Mr. Magoo.
