With the House of The Dragon trailer release and a "next summer" timeframe ... I don't remember S1 at this point but don't remember it being so good as to be worth a full rewatch. Which got me to searching for the title. There are a lot of shows at this point that air so infrequently, it would be nice to just get an RSS notification when any TV show airs its finale.
Best I can find is RSS feeds of torrents, which I specifically don't need. I found one that claimed to be what I was looking for but turned out to be rumours about shows ending.
Ideal notifications would be "The last episode of X just went live. Here's the link to X's IMDB page." I know there are things from years ago I wasn't willing to commit to that may be worth going back to, but that's a different sort of search.
