One Punch Man is that kind of anime that I watch over and over again without any problem, it's the same thing that happened to me when I watched dragon ball, I watched repeated episodes and nothing happened.
Death Note I started to watch it, but for some reason I didn't follow it....
I can't say much about the others because I haven't seen them hehehehe.
Something similar happens to me. Every once in a while I like to watch some single scenes and I don't get tired of it haha. It's the best I can do until the next season comes out xd.
As for Death Note, it's a sin that you abandoned it. I hope you finish it soon.
Thanks for your comment.
