Accordig to Looper, from the article by Phil Archbold (updated 9 May, 2022):
"With so many different genres to choose from, creating a definitive list of the best anime series of all time is no simple task. A show that one viewer sees as being ultraviolent for the sake of it is a masterclass in realism to another. Slice-of-life shows don't appeal to everyone, but to some, there's nothing more comforting. Huge robots doing battle is a bore to many, while others buzz off the idea. From shonen, seinen, and shoujo to mecha, harem, and the ever-popular isekai, there really is something for everyone in the world of anime. However, there's a handful of special shows that transcend the trappings of their genres, and it's those universal crowdpleasers we're going to look at today. From seminal shows that inspired generations of fans and creators to the modern-day classics that stand as a shining example of the medium, we're ranking the 30 best anime series of all time."
