Filtering movies by subgenres

[kingmustard 9]

I know filtering by subgenres has been requested before (I believe most recently five years ago) but it does not appear to have received a solution.

Filtering by Genre only (such as Horror) (please see screenshot below) is very broad when there are hundreds or even thousands of movies on a server.

Being able to then filter by subgenre, such as Horror > Slasher, would be very helpful.

I presume most metadata sources contain more data for movies than only (in the above example) Horror but also some subgenres?

Hi, I've not seen sub-genres on moviedb or tvdb.
