You forgot to add that we all wanna know more about Dragonwhat makes OP great IMO is that their is so much depth to it, you want to find out about Gol D. Rogers treasure, you want to find out if Luffy becomes king, you want to find out what the whole lost history is about, you want to find out about what the significance of the middle initial D. has to do with everything, etc...
With Naruto, i only want to find out if Naruto becomes Hokage or if he dies while fighting Sasuke, at this point thats all it has boiled down to
