And that's how most professional screenwriters proceed. It is true that we need to dismiss our inner critic, our parental side, and let those childlike creative urges flow freely when we write. However, occasionally, we need some adult supervision, and that's the purpose of outlining and editing. It is both, whether creating the movie or the script. There's a balance, I think, between the intuitive and the analytical.
Computers are neutral.
Some writers use the computer as a tool to help them craft great stories. Others become lazy, hoping the software will write the story for them. The reader needs to see what's happening. The narrative description should always present images and actions, but only those that are necessary to move the story forward. Although I emphasize lean writing, I also advise that you dramatize dramatic moments.
