I keep seeing some variation of "why am I so upset?! It's just a show!"
No! No, that is the mind-killer! Art matters! TV shows are pieces of art!
They might be silly, fluffy, brightly colored art, or they might be grimdark fantasy hellscapes, or they might be moderate pieces of hotel art, but they are ART. And art affects us because we're human beings. We see ourselves in it. We learn through it. We tell our histories through it. We teach our children through it. We've been making art since we became human.
This is something that a lot of people spent a lot of time and care and love crafting, so that they could share it with other people who would see something of themselves and others in it. Stories matter! How stories make you feel matters!
We've become so embarrassed by having feelings, especially ones of love and care and grief, but one of the things that OFMD says very clearly is that those feelings are good! They're OK to have and to express and not expressing them in healthy ways can hurt us, very badly.
This is a silly pirate TV show and it matters. How it made you feel matters.
