To put it in the simplest possible terms, I'd say the question is"How good/bad did you find the movie?"

Now if users use their vote to reply to different questions, e.g."How much did you laugh?"

"How much did your partner like the movie?"

"How much did it help you improve your foreign language skills?"

... then the film's aggregate score doesn't reflect anything.

But if you're over there rating like some kind of textbook and I'm over here rating like a hooligan, my PSIs are gonna fall in line with the hooligans and yours the textbooks, we'll hardly need to cross paths. So we can both keep doing what we're doing and never know the difference.

I think I disagree.

• First of all, it would be nice if not only the TCI but also the movie's average percentile also were a meaningful number/measurement. And if half of users translate "so-bad-that-it's-good" to 0 and the other half of users to 100, then that gives an average of 50, which is hardly a meaningful to either group.

• Second of all, the TCI is calculated based on your movie rankings. The TCI is just a mathematical formula. It doesn't know whether the number 70 refers to an "excellent movie" or "so-bad-that-it's-good movie". That's my whole point. If the same voting range is used for both excellent movies and so-bad-that-it's-good movies, then that falsifies the TCI calculations and harms the ranking system.
