I agree, we should support our own no matter what.
I also find it interesting that the theatre world is starting to find stories in the Adult world.
A few of my friends just did "Debbie Does Dallas" The Musical!
And as for it being a movie first, there are many plays that have been made into movies, but end up losing a little of what made the play so amazing. Like "Oleanna" or "A Few Good Men". Don't get me wrong A Few good Men is a great movie, but trust me! You get a good cast and stage that sucker.. Its AWESOME!
