I rag on anime a lot and for good reason. Ninety percent of it is cliche-ridden and repetitive, as with any established genre. Anime is a bit of an outlier because most of its tropes occur in every genre it contains. My personal least favorite is the “panties = funny” thing. Oh, and characters gasping in absolute surprise whenever someone says something stupidly obvious and boring like, “Because we’re friends!” or something.
Let’s move on. Here’s a list of the stuff I want Japan to stop doing so that young American and European authors will stop copying it. Fantasy by young writers tends to take the butt end of a lot of bad anime tropes, so that’s my excuse for posting something only tangentially related to my usual stuff.
