Confusion can be an effective audience emotion, but it shouldn't be the same as being lost (not knowing what's happening). Effective confusion happens when the reader (audience) thinks the story is heading in one direction but it pivots toward another direction. In this opening, confusion happens on pages 4, 6, and 8. This kind of confusion makes the reader want to know what's happening next (getting you to turn to pages 5, 7, and 9). Being confused (in the sense of not knowing what's going on or being lost) doesn't move anything forward. It takes the reader out of the story.

I've read many sci-fi scripts by unsold writers in which the world-building is a rational, step-by-step unfolding (often pages and pages and pages long) so that the reader doesn't get confused. But this approach doesn't tease the reader into wondering what happens next. The only thing you see or hear is the writer talking to you. As with any script, what is left out is far more important than what is added in.
