Story: The story is pretty interesting and unpredictable. You not going to know what going to happen next. Some episodes might be drag on and a big amount of flashbacks are shown in almost every episode so it might be a little bit boring for some people. If you are a patience person then you can make it through the show, the show gets better as time goes on.
Art: The art is a step-up from the original series but I woudn't said that the art is great. I noticed that Naruto Shippuden uses different animation in different arcs. The show never stick with one animation. Some episodes the animation might be really good and some episodes the animation is just horrible. Overall, most episodes have decent animation so the art wouldn't be a big problem.
Sound: Naruto Shippuden's Soundtrack is not as good as the first series. However, The OPs and EDs are great.
Character: Naruto Shippuden have a variety of characters with different personalities. Some characters had developed while some other characters didn't develop much (except their appearance). The characters in Shippuden are lovable so I beleived that you guys will find at least one person that you like.
Overall: Naruto Shippuden might be boring in some cases but if you are patience, you will be rewarded BECAUSE WHEN NARUTO SHIPPUDEN IS GOOD, IT'S GOOD.
