I seriously doubt that. Just because it's what the available data show doesn't mean that that's the popular taste. If you surveyed 100 people who have seen both The Avengers and Godfather Part 2, I highly doubt a majority will regard the former as a better film than the latter. People are in different moods when they rate films, older films don't get rated as often, the scale with which an individual rates different films may be wildly non-normalized...
Website idea[0]: show two random movies, ask them if they've seen both, and if they have, ask the user which one's better without prescribing what "better" means. Repeat 1 trillion times. I'd be much more willing to trust differential data like this.
