I don't dislike anime, but I definitely don't like it as much as I used to. I used to be a weeaboo in high school, but now I find that I dislike a lot of things about anime and manga. First of all, it is overdramatic to the extreme, especially shoujo and I hate that.
Second, I feel like a lot of the stories repeat themselves because the character hierarchy is usually pretty much the same, despite the series, IMO. In shonen, for example, you will have the Goku character, the Vegeta character, and the Krillin character a lot of the time usually with the same perverted, slap-stick type humor. And shoujo, I feel like it's almost always a love triangle with the innocent schoolgirl, the silent protector (like Kaname Kuran), and then the emo boy who only wants "what's best" for the innocent schoolgirl.
Another reason I don't like it very much is because I believe it sexualizes young girls too much. I used to think that it didn't, but now that I'm older I realize that characters like Kinomoto Sakura and Kaname Madoka could have done with dresses that, at least, covered their knees and didn't show off their nonexistent boobs. And I think it's really, honestly, disgusting, and Idc what cultural mindset fuels mangaka to create such character designs, I think it's uncalled for.
And lastly, it's because I feel like male anime characters are really, really misogynistic. One of the worst examples would definitely be Kuran Kaname, who in the second arch of Vampire Knight pretty much controls Kuran Yuki's every move. I remember he even apologized for making her grow out her hair and wear a specific style of shoes. Another bad example would be Vegeta in DBZ, and omg Shigure from Fruits Basket would be, like, a less extreme example, I guess, cause he was kidding most of the time. I know a lot of this comes from Japanese culture, but that doesn't make it okay. Because in Japan, women are treated as second-class citizens culturally, girls are expected to marry at sixteen, to my understand the best jobs currently available for women are to be schoolteachers or secretaries, and husbands believe it is their right to beat their wives. No, I'm making this stuff up. I actually researched it when I was coming out of my weeaboo phase, and I was pretty horrified when I found out about it all. Things have gotten so bad that women have actually started leaving Japan, so they can live more fulfilling lives elsewhere and because of that and the high teenage suicide rate, the Japanese are actually driving themselves extinct. However, that doesn't stop from reflecting their sexist ideology in anime and manga, and whenever I find a series that has too much of that element for me, which is a lot, I turn it off and stop watching.
