I recently got Tubi and I love it. If you don't have it then get it. It is a free streaming service (free due to commercials), but it does have a lot of older shows and movies. As someone who loves pre-woke British stuff they have a lot of that as well.
They have some anime and that is how I saw Fist of the North Star. I really enjoyed it. I am wondering was that based on a Manga or was it a totally original movie? I'd love to get more stuff related to it. Any recommendations for similar anime?
Got anything specific you are looking for? Because I have been on an anime bend recently, but its a lot of newer stuff. On Tubi specifically though, if you have never seen it, I recommend Redline. Its one of my favorite anime movies ever, and I have been trying to find a DVD of it for a while now.
Any older sci-fi anime? Like Robotech?
I like Armored Trooper Votoms. It has a 1983 show and 3 later 80s movies. There's also a 1994 show and some 2007-2011 stuff. It has an old console game, but I don't remember if it's translated.
