It was a random romance show from 2018 that I'd put off forever. Hitting that number made me realize how much I've loved this hobby for over a decade. What was your 100th show, or what's a milestone you're working toward?
Counting shows seems like a weird way to enjoy a hobby. It's just watching cartoons, not running a marathon. Why not just watch what you like without keeping score? That number doesn't really mean anything.
People need to find their own way to enjoy things. If keeping a list makes someone happy, that's their business. I've been in enough hobby groups to know that everyone gets something different out of the same thing. Some folks like the collecting aspect, some like the trivia, some just like to turn their brain off. Let people enjoy their hobby the way they want to.
