4) Maids and Moe
Case Studies: He Is My Master, Hand Maid May, Steel Angel Kurumi, Oh God It Never Stops
Anime is driven by trends, and the worst one to take over in the last decade is called "moe," a magical otaku code word for the art of huge-eyed cartoon girls being cute and innocent and TOTALLY NOT SEXUALIZED NOPE NOPE NOPE. Another ugly trend: maids. Specifically, young maids in frilly outfits bending over and being subservient to their "masters." Combine the two ideas, and you get a good argument for giving up on Japan's animation industry altogether.
The above clip comes from He Is My Master and is typical of this particular genre. Watch as underage girls wear maid oufits and whatever else geeky viewers might want to see! Chortle as our heroines are sexually harassed by a pet alligator and a rich kid who in no way represents the target audience! Be absolutely shocked to find that this show was co-produced by Gainax, the studio responsible for Evangelion, The Wings of Honneamise, and...well, lots of pervy Evangelion merchandise and an attempted-rape scene in Honneamise. On second thought, don't be all that shocked.
