Like, f’rinstance: character names! Bob and Todd. Sally and Sarah. Virginia and Veronica. Sauron and Saruman!!
Here’s an image that’s intensely confusing — a map showing the three Superstates in George Orwell’s novel 1984. Oceania, Eurasia, Eastasia. (two of which are hella difficult to tell apart, but that’s another conversation). It’s just a map. How difficult could that be to get right? A map. Simple enough: a color for each Superstate. Hard to mess up?
Think again.

Oceania and Eurasia are almost the EXACT SAME COLOR. And, Eastasia is almost the EXACT SAME COLOR as the ocean!
At first glance, this map is incomprehensible.
And, gentle writer, a first glance is ALL you get.
Your Screenplay Sucks!
