I have to say, I hesistated to watch Naruto for a looong time. But when I finally did, I rushed to see Shippuuden. I think that the name itself,in english the Hurricane Chronicles, is quite accurate. Naruto Shippuuden will take over your mind and senses with speed and strenght of hurricane.
I think that the story is the best part of Naruto,at least for me. If you look all the way through the comedy,battles and 'dattebayo', you'll find an amazing story about friendship,betrayal,fate,view of evil and bonds. And I mean it.I'm not much emotive, and I don't usualy cry while reading or watching TV,but Naruto,manga and anime,made me cry.Twice. Of course,there are really annoying fillers,but that's not the real story,no big deal.The story continues the one from Naruto series,two and half year later. Naruto returned from his training,ready to find Sasuke and bring him back,whatever it might take.But along with new allies,new enemies appear,and Sasuke isn't willing to come back. But like would Ńaruto himself say ''Give up on me giving up.''
Animation was one of the biggest reasons why I refused to watch the first series for so long. But that doesn't apply for Shippuuden,though. I think animation is pretty good,really. There are weak moments,when you sit,stare and think 'I would do it better'(Yes,I mean Naruto vs Pain) but most of the time is enjoyable- of course, I have seen better,but also worse. It's average and pretty,and suited for Naruto :D
Sound is,well,for me is awesome. I think it really fits the situations,the feelings,really.Sometimes you won't maybe even notice it,but it's really good.It's sad when you want to cry,and comedical when you burts out laughing.Also openings are beatiful,and endings too. You heard it once,you have to listen to it all the time. That's what sound of Naruto Shippuuden is.
my favorite opening,heh :D But they are all the best :D
Characters in Naruto are really well done. Everyone must find some character he will like,even if it's pervy Jiraya, cool Itachi, agressive Sakura or baka Naruto. You will love them ,you will hate them. Naruto,main character,didn't really change from the first series. Well,probably only Sasuke changed, a lot.Some may say they hate him,but when you watch the story carefully,you find out,he has reasons to be what he is. That's the greatest fact about characters in Naruto. They all have reasons to be what they are,even if it doesn't seem. There are some stereotypical characters,but also those you can't put in any category. A lot of new characters come and die through the series,but almost every single of them leaves his own 'footprint' in the story.
I say WATCH IT! Naruto Shippuuden is goddamn popular and for a reason,believe it!!
p.s.watch in original dub with subtitles
