It’s completely beyond me why scripts get rushed out the door before they’re at the very least solid. Sure, a production company might make their money just a little bit sooner but they run a massive risk of losing all of their money making a movie that completely bombs.
It’s impossible for every script to be a masterwork, but holy crap it seems like an audience wanting a competent script is too much to ask. It’s not like there’s a shortage of aspiring writers that can take a crack at a script until it’s at least passable.
