*sigh* U_U if you insist...
well i think i was wrong to say "you need a good brain to follow it"
But...we have had alot of mysteries and technical facts from kishi right. well the first one i can say is; we first knew the hokage died...but how all that happened in detail was a mystery , and then kishi explained it, he not only cleared the air but sprung some more facts in the equation (kushina being jinchuriki, minato sealing half of the kyuubi in death god, knowing tobi was genually behind the plan that day etc) <- to me thats technical and "deep" .
another example can be the identity of tobi , first introduced as a nobody, then he had screen time and re-introduced as madara(the main villain) , any normal story righte/manga artist will end it there; but not kishi...bam hes probably not madara and hardcore speculations begin up in this forum, the dumb kids will go with tobi=obito and the others will actually play around with facts, foreshadows and hints. now thats why i think naruto is for someone who wants a deep and technical manga, well in the first part of naruto it had almost the same vibe as one piece but it flipped in shippuden, people would dislike shippuden but i actually LOVE it, i liked naruto because we wer still getting to know alot of new things, but shippuden is us knowing where all the characters we already know grow into something more important and thats when everything gets serious , and i wonder if thats ever gonna happen with one piece because at the moment its jokes all round
