If you have any desire of working in the film industry the reality is that critics never leave. Ever! Although they don't have to be as scary as they may seem. Sure some of them are cruel, and will hit you right in the gut of your creative instinct. Others are tasteful and have some valid criticisms. I get it, it's very hard to listen to someone pull apart something that has practically become a part of you. But if it will make you better it's ultimately for a good cause.

ScreenPicks Movie Reviews: Gone Girl, Annabelle and The Good Lie
Even the worst of the critics and reviews can be beneficial in some way. Although you may not agree with the arguments the person made you are still getting to hear how one person has viewed your film.
If you constantly write what would only make sense in your own head it would not sell well because modern audiences need to be able to connect personally to the story. Sometimes your story might not be coming off the right way for the audiences. They might be misinterpreting some things. Reading a bad review wouldn't offer any technical advice, but it would show you a version of how your story is being interpreted.
By taking a step back to try to objectively identify with the reviewer you can start to incorporate those criticisms in your storytelling. That way your stories become more universally appealing and then even start selling well.
Always remember, consider the source.
