Ray Bradbury was fond of the sentiment above, that you shouldn’t feel ashamed or inadequate because of the things you enjoyed. The set of cultural memes and art you like are a fingerprint of your personal aesthetic, probably as unique as you yourself. There are far better and more worthy worries out there.
That isn’t to say we don’t grow and learn, and trying out new things is part of that exploration. But the taste judges don’t deserve space in your head to demean what you like. No guilty pleasures.
There are plenty of reasons to celebrate the stuff you like that is critically acclaimed or praised as best. What about the things others disparage that you still love?
The answer is still to celebrate them. Ray Bradbury once said (probably more than once, as he gave plenty of talks over the years), “Never apologize for your taste.” Indeed. The things we like are an essential part of who we are. And, as artists, they color and flavor our work.
You can definitely benefit from trying new things and expanding the possibilities of what media you experience. But never be ashamed of what sparks love and excitement in you. We should be trying to become ever more truly ourselves, and that includes everything we enjoy reading, watching, and listening to. The set of things that influence you are unique to you.
