[...] even though I can't really see how "studio-logo-segues-into-film" could possibly affect my opinion about a movie.
Here's a quote from Wikipedia that should shed some light on the issue of weird keywords coming up
Wikipedia wrote:The conventional dictum that "correlation does not imply causation" means that correlation cannot be validly used to infer a causal relationship between the variables. This dictum should not be taken to mean that correlations cannot indicate causal relations. However, the causes underlying the correlation, if any, may be indirect and unknown. Consequently, establishing a correlation between two variables is not a sufficient condition to establish a causal relationship (in either direction).
This basically says that just because it appears that you like those movies that have 'shot-in-the-head' as a keyword, doesn't mean there's a causal relationship between a movie having that keyword and you liking the movie. It might just be a coincidence. Of course, if everything about these correlations would be coincidence, then there would be no use for these recommendations. However, I trust that at least some of these keywords, as well as the other parameters do have a causal relationship with you liking those movies
I like what I see on the aesthetic side too, keep up the good work! And once again, thanks.
