Show a detailed list of all the factors that went into each movie recommendation.
I'd love to see a list like:
You loved star wars, we think you'll like X because they both have:
- The hero's journey
- Parental loss
- Magical wizard helpers
- Fight against evil
- Political oppression
- Some romance
- Set in space
- Childhood innocence shattered
It would require that you categorize movies with a lot of granularity, of course, but that's the kind of data I imagine a movie recommendation engine has?
