Can someone please explain the weird way my brain handles movies?

The same applies to all fictional videos meant for entertainment, including TV show episodes, video game cutscenes, etc.

Whether or not I like a movie is entirely based on re-watch patterns, every one is different, e.g. some I only like every second time I watch it. I don't think there are any movies I always like, or any I always dislike, it always follows a pattern.

No, I'm not autistic. I don't choose to like or dislike movies, it just happens. And by the way, when I say "dislike", that doesn't always mean I don't find it entertaining. But when I say "like", that always means watching the movie simply has a good feeling, kinda like eating food that tastes really good.
