Once upon a time I was reading One Piece.. now I'm way too broke to buy those volumes. The story is still good and I don't get the hate.
Anyways, Nickelback is the only thing sucking in here.
Same reason as to why everyone hates Naruto. It's entry level anime that is really, really bad compared to other anime that isn't shonenshit. Posting about the "big 3" anime on a site like 4chan will get your thread spammed and sage-bombed.
