Chore: an unpleasant but necessary task
I have to do laundry. It's something I need to do or else I won't have clean clothes to wear. Eventually my dirty clothes will stink and/or get destroyed from me not cleaning them. They pose a risk to my general well being, so I must clean them, even though it's not something that I want to do. Maybe some people like doing it (I doubt it but whatever, for the sake of the argument). It's still a necessary task. That's what makes it a chore.
I don't need to watch movies. There's nothing at stake for me not watching a movie. There's nothing necessary about it, no one here is holding something over my head to watch a certain film. It's just something I do for fun. If it starts becoming a chore for you to watch certain films, then don't watch those films.
