Yes, i agree with both perspectives you are giving, the one on DragonBallZ and naruto - I see it this way, no matter what we watch in life, it all depends on who we are, who I am watching it, this way any story, anything can become a point of self-investigation and self-transformation through realizations. We can have sophisticated anime and other TV series, but if brainwashed people watch it like Zombies, then the meaning or the deeper meanings within it is lost, for example, when the matrix came out the firts time, everyone I knew only saw it as an awesome Action movie, nothing else, ten years later I watched it again, and due to my perspective that has changed in that time and how I have developed, watching the matrix again blew my mind away, and I questioned msyelf, how come ten years ago it was simply an action movie to me, now it is a LIFE changing movie, because those I watched it with ten years ago, only cared about their cultures/religions and nothing else, so nothing new could ever come in and change their view/life.
