Sounds about right.

A good counterpoint to all those script literalists who say we can only write scene description which an actor can act and a movie audience can see. No commentary. That's just plain wrong. All one need do is read actual movie scripts and you see pro writers do in most every script. You have to be judicious, but if it conveys character, adds to scenes, and provides entertainment, it can make for a more "pleasurable" read.
