Series that emphasise the presentation of struggle and dramatic event(s) through culminating the portrayal of the experience to that point visually or by some other means.

This is a part of a series of stacks that are about artistic tendencies in anime (and that border the fine line between sophisticated and pretentious).

This stack is a work in progress.

Choujin Densetsu Urotsukidouji Movie should be included here, but is tagged as hentai on MAL, so otherwise this list couldn't be public.

List of anime for "elitist". These anime have been considered as "deep" animations by various critics and analysts.

In this compilation there are animes with quite complicated stories that are not recommended for all audiences. As they are: cult, artistic, experimental, avant-garde, underrated, psychological, philosophical, unique or mind-blowing anime.

This list has a part 2: https://myanimelist.net/stacks/4197

Anime series that are great and underrated.

Series that utilize philosophical approach when it comes to their portrayal of society. Usually featuring "outsider" perspective as a main vehicle for the exploration of the "society" and the philosophy.

Essentially a character that acts outside of the "society", that is at focus of the series, as far as the philosophy of the character goes when it comes to approaching the society. This role can also be called as the "observer". A role that acts as a tool for the audience to be able to gain understanding of the contrast of the philosophies of the "observer" and the supposed "society".

This approach enables that the audience is able to experience the contrast of these two philosophical approaches when it comes to the society and is able to experience often both sides the "observer" and the supposed "society" that is approached through the eyes of the "observer".

These series often also propose an alternative approach to the philosophy that is in contrast with the approach of the "observer" and present us an alternative way of seeing the "observer" through the eyes of the supposed "society"

Por algum motivo esses animes me passam um feeling comum entre eles, uma vibe meio de um anime não muito conhecido e que é mais diferentão. Talvez algo que fuja um pouco do design batido de uns animes mais populares. Não uma fuga total, mas algo... diferente, eu acho.

Psychological animes. From dark animes that make you think, then more normal ones that are still psychological.
Still adding to the list!

From late 90s to early 2000s. Organic animation with a hint of depression, existentialism, cynicism, semi-realistic artstyle, fear/ embrace of technology after the economic bubble burst of Japan in 80s.

The list is still under construction

Releases which draw in meaningful ways from the named esoteric Hellenic spiritual tradition in their symbolism, themes, or both (Alchemy, Kabbalah, etc.). Most elements from the practice are fairly perennial in their implementation, and this is something up to interpretation, so I've tried to be strict without relying on explicit references.

These 10 anime that include complex, dark and weird stories will make you feel like an elitist and an edgelord

Dark gothic aesthetics.

These anime take their time to develop, but once they do, there is no turning back.
Some might appear to have no plot or little plot continuity. A few of these anime might take even entire seasons to develop.

Some of these are tagged as such in AniDB, some others are from my experience watching them.

I am only adding the first season/entry of each franchise
