While definitely a movie designed for children, there's a good amount of solid love that doesn't make it feel patronizing or pandering. A very cute, sweet, and emotional movie for all ages.
Naruto
While it has iconic moments and largely set the stage for anime and shonen in particular, Naruto does not age well; there are plenty of better shows. It is very culturally relevant to be familiar with, however.
Jojo’s Bizarre Adventure (Parts 1 & 2)
Jojo’s is an extremely over-the-top presentation of a lot of dramatic, sexy-posing men, and it is a beautiful thing.
Re:ZERO -Starting Life in Another World-
Combine your average Isekai fun with the dread of Majora’s Mask and the psychological rattling of Doki Doki Literature Club.
DanMachi: Arrow of the Orion
Pretty standard TV-anime movie with not-necessarily-canon story, but if you can get a hold of it, worth checking out.
Sword Oratoria: Is it Wrong to Try to Pick Up Girls in a Dungeon? -On the Side-
More interesting and classic RPG fantasy vibe than the original series, but more fan-service and not quite as much charm/heart.
Is It Wrong to Try to Pick Up Girls in a Dungeon? (DanMachi – Seasons 1-2)
Beneath all the tropey fanservice and boob jokes is a charming show with a good amount of heart.
Overlord (Seasons 1-3)
A fun and good watch but a bit lacking in direction.
Sword Art Online: Ordinal Scale
While not without plot holes and a slapped-together ending, this grounds the series back down to its roots and keeps asking those very relevant questions.
Sword Art Online II (Season 2)
This season goes deeper into the psyche of the characters and explores the concept of Virtual Reality applications, ramifications, while also showing both the benefits and risks of immersing oneself online.
