I seen Naruto a few times, and it bored me, its too much of a cartoon base rather than anime to me.

nothing wrong with dub or subs, why even argue about that? its just preferance

bleach is good but the story doesnt seem so exciting, after all, we are waiting for Aizen and the follow battles to come with it.

One Piece is a great Manga, its actaully got depth and feeling to it, but lacks substance compared to Gantz.

As for DBZ, thats too simply with the story..look how once a strong enemy comes, it takes them all they have to defeat them, then a few more arcs, there is a new enemy which is much stronger than the previous and make the previous look like nothing and in terms of power, it is based on 'power levels' enemies with stronger power levels coming one after another, is there any change?
