Man,get that pseudo insight about technology out of here.
They had pretty advanced technology from the beginning,also go back to the chapter deidara kills himself in order to create that mega explosion.
Modernized buildings are in the back of panel.The series takes place in a village run by ninja.It doesn't focus of the rest of the world which you obviously just now realized exist.Congrats give yourself a pat on the back.,.then take it back for being stupid.
calm down, i know that the hokage won't go on solo missions, thats not what i meant, in the trailer the village is attacked and a hokage will protect the village with his life so i hoped kakashi gets a bit action time only to show what he has got without the sharingan, but when i claimed that point i wasn't aware of the extra novel about him so it is all right.
About the materialism thing i won't agree with you, the little technology which was there before isn't comparable to the new konoha which was shown in the last chapter.
And naruto using a macbook is the high point, in the trailer they got little flat screens inside there hands so don't come here and talk to me like I'm exaggerating because I'm not, the anime got legendary because of ninja styles and thats the thing i misses when i watching the clips about the movie, but thats only my opinion so please stop playing the moralizer
