Review Detail of AirheadPufferfish in One Piece: I wield thunder and lightning

I'll be honest I don't really know what it is, it's not like I dislike the story, but somehow there's something wrong fundamentally that irks me every time I read 4 or 5 chapters my mind starts wandering and I end up doing something else or reading something else, am I the only one? have I finally gone insane by reading too much?
