Anime is classified into different genres. And if DBZ has too much fighting doesnt give you the right to undermine it as an anime. Besides, what part of it is childish? Would you let children watch, such violence? take off your foe's head just in one punch? And making an expression like he is enjoying it, is that what you think is childish? Surely, kids enjoy it but they needed to censor it to actually broadcast it on CN. DBZ isnt just a childish cartoon, I guarantee you that.
