If I'm deciding whether to watch a film for the first time, I really don't understand how whether or not other people would want to watch it a second time helps me make my decision. "We rate movies on two criteria - ‘quality’ and ‘rewatchability’, so you can admit to your guilty pleasures and properly capture the feeling you get when a film leaves you exhausted." You are using rewatchability to infer some potentially helpful labels ("guilty fun", "exhausting but worthy"). But there's no guarantee that those inferences are safe/generalisable across viewers/films/genres, or that people who see a rewatchable axis will know to interpret it like you do...
