picklesandcheese Sometimes the best ideas are the simplest ones of all, annd I'm glad someone finally thought of this. Commentary The Musical is featured on the Dr. Horrible's Sing Along Blog DVD as an extra feature. Anyone who has seen Dr. Horrible's Sing Along Blog and hasn't purchased the DVD of it should do so for Commentary! The Musical.Commentary! The Musical is commentary track, but with songs (ironically enough more songs that the original feature). It's just as good as the original Dr. Horrible, and I hope they'll come out with a Commentary! The Musical soundtrack. The cast and crew sing as themselves, not as their characters (although I'm sure there are several things that are exaggerated for comedy). The songs of fun, catchy and often hilarious. And the nice thing is a lot of the cast who maybe didn't have a much of singing role in Dr. Horrible, have a chance to shine here, such as Stacey Shirk's (Groupie #2) song "Ten Dollar Solo", or the hilarious number by Simon Helberg (Moist) "Nobody Wants To Be Moist." In fact the supporting cast sings a great number about who's really the star of the show called "It's All About Me." In order to appreciate Commentary! you have to watch Dr. Horrible first, or most of what is sung/said (yes there is some speaking on Commentary!) will make no sense. As long as you've seen Dr. Horrible you'll love Commentary! The Musical. All the songs are just fantastic. Another reason to love Dr. Horrible's Sing Along Blog.
