I wana do a top 50 but only for the past 5 years since there’s been some fire drops since then I’ve seen all the classics but would like to see what everyone thinks should be top 50 since 2018

So far
I got
Frieren
Heavenly delusion
Eminence in shadow
Jjk
Mashle
Let’s keep it goin

hells paradise
platinums end
solo leveling
chainsaw man

ragna crimson

AoT
Demon Slayer
Highcard
Kingdoms of Ruin
Unwanted Undead Adventuer

What Genre defines the selection?

Example: There are 218+ "Isekai" to select "Top 50", however some of them have a season or more BEFORE 2018.

Hmm, what now... what about Titans? (whatever the title is, but the story is based on people getting eaten by Titans etc)

I like the idea... I would also think a minimum of five(5) different Genre and 50 listed, then you can take those 250 and minimize the selection by how many of them fit two(2)+ different genre out of the 5 selected.

Example:
Action
Magic
Sci Fi
Isekai
... ???

The Rise of the Shield Hero (Isekai)

There's been so many good series, but you got to have at least a sub-genre to do a top 50. Some favs of mine recently (In no particular order):

1. Mushoku Tensei: Jobless Reincarnation
2. Goblin Slayer
3. The Apothecary Diaries
4. BOFURI: I Don't Want to Get Hurt, so I'll Max Out My Defense
5. How Not to Summon a Demon Lord Ω
6. Interspecies Reviewers
7. Sword Art Online

Pretty much all Isekai animes are great imo lol

Frieren
Jujutsu Kaisen
Demon Slayer

if it wasnt for "since 2018" i would add some of my fav animes such as kotoura san or sakamoto desu ga or deathnote etc
so many good animes
