Anything that isn't super mainstream. Like a character starting off weak, and continues being weak for half a season, then suddenly discovering they have a hidden power sealed inside them lol. I've seen this so much that it got boring.
I prefer when they use the very thing that made them weak, and work hard to become stronger.
Just not similar to 'Kirito' and other mainstream characters. I hate creators and writers say things like 'the watcher must imagine that he is the protagonist' that's their reason for creating lame characters cus they target a very WIDE of audience.
