Alright now that this is over, my over all review of Gaiden, and the Naruto series. First addressing its problems, because believe me...there are many.
Problem 1. The villains. Remember when Naruto was cool...back when the Akatsuki leader was ominous, mysterious, and completely evil. Yeah, what happened? he turned into a little kitten who happened to serve another kitten villain, who happens to be under command of another kitten villain, who guess what...is replaced by another kitten villain. The villains at the end of the story were terrible. Nagato served Obito, Obito served Madara, Madara got b**** owned by a plant dude who I am currently in doubt whether was male or female, only to have this whinny witch who didn't do jack ^^^ get owned by these two whinny teenagers who didn't do jack **** Which brings me to my other problem.
Problem 2. The heroes. At the end, what did they truly accomplished? What was the conflict during the final war arc? Other than beating up a whinny uchiha. There was no accomplishments, and no consequences. At the end all we got was Sasuke the guy who always sought the love of a family shown abandoning them for 12 years...Only to come back in Gaiden and doing the same thing all over again. Naruto who sought the need of having a family suddenly doesn't want to spend time with his kid, being too busy with the Hokage office that amounts to nothing now that the world is at supposed peace. Which reminds me...is it really at peace. I mean Naruto is the Hokage leader of a village...not the leader of a nation, he still has to follow orders from above. What if a new leader of one of this many nations takes the reins of power and starts going nutty declaring war left and right.
Problem 3. As mentioned, this whole thing was useless, Gaiden was useless .remember Jurassic Park 3...well that was Gaiden. Gaiden was Jurassic Park 3, when the Mother F*** T-rex got killed by that dinosaur that looks like Daffy Duck's beak after it got shot. You remember that one...remember how it felt...well this is how it felt to read each page of Gaiden. Nothing happened...it was pointless...
Problem 4. It was way too long, and dragged on forever.
Problem 5. It was a marketing scheme to promote movies.
Problem 6. Characters who a normal person would question their morality, apparently got everything they wanted.
And that is just to name a few.
