As someone who spends most of his free time either watching or torrenting anime (I never watch shounen though), I don't know many alternatives myself. The closest thing I've found that brough me the same sort of feeling was arthouse films, the French new wave films specifically because a lot of them are kind of what slice of life anime would be like in live-action form. If you want to know more, you could take a look at /film/. I also read the occasional non-fiction book but that's more for the purpose of educating myself on a certain matter and training my attention-span than really out of pure enjoyment. I've never been that into vidya outside of a short phase ~6 years ago which quickly ended when I realised that the amount of interesting games for PC are very limited.
For me, part of the appeal of anime is the sheer amount of it; you could watch anime every day for years and still not run out of stuff to watch. There's always a certain era or genre that you haven't fully scratched yet. That's most likely why I never managed to find any alternatives, I don't know any medium (that appeals to me) that'd allow me to spend years going through hundreds of entries into it and still only have reached the peak of it all. I can understand your alienation from anime, don't base the medium purely on its most popular entries. The type of stuff normalfags online recommend to newcomers are sometimes some of the worst or mediocre series ever made.
