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?
It's pretty top notch. I enjoyed it as well.
I don't have much for similar anime, unfortunately.
Some of my other favorites, ninja scroll, ghost in the shell, made in abyss, naussica (almost all myazaki, actually), and dorohedoro were all good.
There is a ton of good anime; far too much to list.
