Of course, it's everyone's own decision what they do with their free time and it is not my place to judge anyone, but you could at least give a good idea a chance, right?
Fwiw, if it helps to know, I clicked "Explore" in the web browser (this works in both Firefox and Chrome, although ofc it would bc it's just a URL issue!:-P) and then clicked Movies & TV, and that link is what it points to right now.
Oh I see now... on a mobile device I did not scroll down, but the Explore menu has both Feeds, up top where people using a mobile web-browser would see those first, and then Topics down below. Anyway that Feed is what most people will most readily find when looking for that content, so it may be good to try to get those communities added, by contacting whoever owns it, or making a new one and replacing that menu choice with yours, or some such?
