There's actually a trick to writing in script if you're not actually writing a script. Once you realize that, you can get a lot done with it; as a format, it is best deployed if you're writing something that's heavily dialogue-dependent with a lot of meta-humor in it, in which traditional prose transitions would actually get in your way and hinder the story.

I'd never try it for a serious piece, tho.
