Thats an interesting idea. I'd still be surprised though if that didn't correlate with some movies. If someone hates Napoleon Dynamite due to feature X, then they should dislike movies that have X as well. Or, at the least, avoid watching movies with X. So, if your theory is correct then I see two possibilities: 1) The pointy bits are themselves strange and don't appear i other movies. This goes back to "the movie is strange" again though... 2) People who dislike these traits avoid movies that have them and the algorithms don't take into account what movies people haven't seen (or that taking it into account is very tough since most people haven't seen most movies). Not sure which is more likely.
