From this horse with high heels to this dog with tails for legs to "I fused Adolf Hitler and that beautiful afghan girl from iconic National Geographic photo cover", along with just so much generic and weird waifu shit.
Also more cowboys than you'd expect.
Honorable mention to this monstrosity that somehow manages to combine waifu trash with weird monarchist shit.
People have always been writing terrible fiction. Trawl the depths of AO3 and fanfiction.net, look at the great mound of rejected novels by aspiring authors. Artistic mediocrity is a part of the human condition the same as artistic excellence.
For the most part, the "ineffable something" required to write a good book is years of practice, an editor and the barrier to entry that is convincing a publisher to take you on.
