1. Maybe your popularity value should include more types of "views", maybe both Netflix-internal
(like total dvd rental, the last X days back, or since forever), and netflix-external (like
total number of movie-tickets sold, worldwide or in the same country).
2. Shouldn't the word "zone" exclude the twilight movies altogether, or at least boost the
results with that word in the title?
3. Maybe the popularity has a too much of influence on the score?
4. I never said my reasoning about normalizing popularity was applicable to your use case.
On the contrary, like I said before, I focused on our own use case.
