For me the most reliable place is NarutoSpot.com. This is where iv'e watched all the episodes i ever saw. It has every episode 或者 火影忍者 and Shipudden dubbed and subbed.
narutoget.com is one of the best 你 can watch all of the seasons from the first 火影忍者 series plau the 电影院 and all the latest episodes of Sgippuden plus those movies! Good Luck! :)
i watched just 火影忍者 on Netflix but 你 can also watch it on theier website naruto.com if it doesnt come up then go to 火影忍者 shippuden.com then on the bottom there is a link/picture that will bring 你 to it, 或者 你 can watch it on Vizanime.com, the only problem that it has cermercials
