Sometimes you've been working on a project so long, you forget the basic, simple, screenwriting 101 rules. In the tangle of rewrites and motivations and act-outs and polished description, be sure to go back and ask yourself:
What was the theme of this episode that I had decided on?
Do I have interesting visuals?
Do my scenes have emotional shifts? Do people leave or end scenes different than how they started?
Are all my scenes crucial to the story?
And, most simply, but most importantly: Do my scenes all have conflict? People wanting things, and obstacles getting in their way?
