Why does everyone that has a connection with someone that gets reanimated have to be just at the place that those reanimated people attack? I hate it when someone gets reanimated and end up fighting against the people that stood them the closest. I'm glad Dan never got to fight Tsunade. Sure they made him use a ghost jutsu and meet up in the end, but still.
Suigetsu could have been cool to see how he would react and deal with it but Juugo would just be boring. Juugo is nothing but a tool. "Sauske wants to destroy the world so now i'm gonna destroy it too. Not because i want or agree with it but because someone that is dead believed in Sasuke. Oh now Sasuke wants to bake cakes for the rest of his life. I'm gonna bake cakes too for the rest of my life". TOOL. The whole Sasuke's will is Kimimaro's will is flawed from the start since Kimimaro wanted to become Oro's new body, and that was obviously not what Sasuke wanted.
