Forgiving baddies because friendship and the cycle of hate must be broken nonsense
Main reason I despise Naruto now. Sasuke should've been beheaded and buried UNDER the prison. The Second Hokage was right. Lord First should've killed Madara when he had the chance and quit the stupid moralizing about forgiveness crap.
Damn near every issue in Naruto had its origins in one Uchiha or another being a emo-freak and pretending his pain was the "worst one ever" and deciding only he had the right to "fix/punish the world."
Which is amusing considering they had just as much dirt, if not more, than most of the people they were blaming for their problems.
But, if it wasn't an Uchiha playing victim and causing issues, than it was Danzo's fault. Yep.
Every issue was an Uchiha's making, or Danzo.
As for pet peeves, my biggest one is when a story suddenly becomes preachy on some hot-button political issue with no hint that it is about to do this. Even if it is an issue I agree with, this just grates on the nerves, and is even worse when it is one I disagree with.
If it is open about it at the start, that's fine (I can either skip it or give it a chance for the story/writing, regardless) but if it suddenly goes into preach/rant mode with little or no hint it was going to go there? Ick.
This is the reason I absolutely despise the He Who Fights With Monsters series. This is the guy who decided to read Karl Marx's Communist Manifesto while writing the story. He just derails into rants about shit, and occasionally he eats up an entire chapter with it. I bet the guy has a sickle and a hammer hung on the wall of his bedroom. Anyone whose read that series KNOWS I'm NOT exaggerating. And yet it's popular as hell. I can't understand it myself. But I guess I don't need to.
Nationalism in chinese novels
I normally don't like this, but there are two examples I let slide and continue reading. South Korea bashing North Korea, not because I have a hate boner for North Korea but because the amount of times I've read South Korean protags actually going to meet Kim Jong, it always ends with Kim Jong being their biggest fan. I've never read where they actually kill Kim Jong. Its an interesting view into the South Korean mindset regarding their Northern neighbor.
Then, it's when Chinese authors talk about Taiwan. Chinese opinions of Taiwan are about neck and neck with the average Americans opinion of North Korea. You would think there are several hell gates open in Taiwan at all times and I'm always more amused than annoyed while reading it.
