I agree that a lot of what Hollywood produces is garbage. That doesn’t mean that some of the films don’t have artistic qualities and good writing, even if the message is ultimately evil or otherwise objectionable. One of the reasons why many of the classic Hollywood films are so good is because the writing is superior and the production is very good. I’m sorry but Kirk Cameron’s shoestring budget junk doesn’t even compare.
About Hollywood, if the subject is bad no amount of writing is going to save it. A bad story is a bad story.
