Netflix genre codes and TIG
I just ran across an interesting article about specific Netflix URLs you can type in your browser to see any of thousands of subgenres:
https://inews.co.uk/essentials/culture/television/netflix-uk-secret-categories-codes/
The first result under "Cerebral British Dramas" and "Cerebral British Movies" is "The Imitation Game." It's also the second result under "Cerebral Dramas." Or at least, it was for me. Ever since Netflix changed their star ratings from "the rating given by other Netflix users who've seen this movie" to "the rating we think you would give this movie," I can't be sure whether other people will see the same results.
BTW, the above article has a link to a site that gives the full list of known codes. (I.e., known to fans who've tried to discover them; we can't be sure that there aren't others.)
