Wow, really? If you knew about the lore than you would not be even surprised. Solo Leveling is "John Wick" of anime world. There are almost zero moments where Sung Jinwoo just rest. Mild action will be in Ahjin guild arc, but Double Dungeon revisited, Japan Crisis Arc, Guild meeting arc and fight with monarchs are completely filled with action. If the action will be as intense as in Bleach TYBW (well my humble guess is that it will be way more intense) than this might be the best action anime ever (as a whole).

I dont agree with Daima. While it explains some things (i.e. who are Namekians) it was built on DB GT basically. From my point of view it is basically rip-off and while it had different ending it is not even near top 50 to watch.

to idk: The title is "watch at least in lifetime", so One Piece should be included, but that would not be top 8, but top 9 (also I am questioning the ranking anyway).

As for titles that are for newcommers - that is highly questionable, Neon Genesis Eva or AOT are from my point of view not the first pick which I would suggest to newcommers.

I am not sure if I would agree with ranking (except Solo Leveling which stands out - despite being the youngest one it is really great and seing how the action is handled I have zero doubt that it will be bad in future).

However I am missing animes like Full Metal Alchemist, One Piece or Initial-D. There is also one anime that comes into my mind - Dragon Ball Z (despite its fillers and age I still find it it superior to Kai one, mostly because it is "darker").
