There's a lot of light and fluffy fare in anime. Even back in the 90s when I was used to sex, violence, drama, and strong character lore in my anime, I discovered You're Under Arrest and was a bit surprised to discover that it pretty much went nowhere, just an episodic series full of funny things for the characters to do. Especially surprising for a show about police officers, which in American media usually means it's a "procedural" with particularly dangerous criminals and high stakes. But in YUA the officers mainly deal with petty criminals and get up to wacky hijinks. More recent series, like Azumanga Daioh and Lucky Star, are pretty much just schoolgirls doing cute things. And maybe that's just the energy you need sometimes rather than, say, the horror and drama of Attack On Titan.

To paraphrase Brad Bird, anime is not a genre. It's a broad art form that encompasses all genres. This is a common mistake for Western viewers of anime; even in the 90s it was marketed to us as being all dark, twisted Liquid Television stuff. But yeah, actually, most anime is created for and marketed to kids and teens. In Japan, if you're an adult consumer of anime, your peers may wonder what the hell is wrong with you and why won't you grow up. (Manga is different; plenty of manga are produced for adult consumption, and these are fairly serious in tone, and may lack the fantastic settings or big-eyed character designs Westerners associate with the medium.) Adult anime otaku in Japan are viewed with the same bemusement and contempt we might have for, say, the grown-ass men who are fans of My Little Pony. This may have changed more recently, as the Japanese government has leaned into the idea of anime and manga being important cultural exports through its "Cool Japan" publicity program.
