Some that haven’t been mentioned yet (I think):

• Kuuchuu Buranko: This one uses rotoscope animation. It’s a “trippy” anime that deals with various mental health problems (mostly OCD). I think this is one of those anime that almost nobody really knows about. It’s very obscure.

• Aku no Hana: This also uses rotoscope animation. I actually never watched the anime and only read the manga. It’s one of those psychological types but it’s well-grounded in reality. The animation itself is weird however. Probably because rotoscoping at this level is uncommon in anime.

• Monogatari Series: The notoriously “immoral” anime series (and one of my all-time favorites). Generally speaking, anything by SHAFT have really unique visual storytelling which includes Madoka Magica and Sangatsu no Lion.
