Scripts are a house of cards and you can't just reach in the middle and pull out the middle card because the house of cards will fall down. But at a certain point you almost have to allow that house of cards to get knocked down a few times because you need to make it sturdier. How many times do you hear, "No, that doesn't make sense," or "Why would this happen?" That was a mistake. You shouldn't have those moments, because the moment you're knocked out of the story, then you're dead. And all you can go is moment to moment,or joke to joke. And that's gonna wear people out.
