This is one of the most naive post I've seen in this thread. First off, yes, you're right when you say the manga isn't ours. However, you need to remember that the mangaka don't draw manga for their own self-satisfaction, they draw it to entertain the readers and sell copies to make money. The consumers have a right to complain when they believe that what the mangaka is churning out each week is subpar or just plain bad because really, it's their opinion that matters. Secondly, something being generic is not an opinion. If a manga has reccurring cliches that are common for its genre, then it is in fact generic. That is what it means to be generic. Anyway, the only thing I can really agree on with you is that I'm also happy that more people are reading Yaiba, because the more exposure the better.
On another note, about a month ago my friend gave me a Pokemon booster pack and earlier today I was looking at the names of the artists and I discovered that our very own DemizuPosuka did the art for a Mantine card. Honestly did not expect to see his name on something like that, and I'd love to see more Pokemon drawn by him because I love his defined contour style.
