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 или Наруто and Shipudden dubbed and subbed.
narutoget.com is one of the best Ты can watch all of the seasons from the first Наруто series plau the Фильмы and all the latest episodes of Sgippuden plus those movies! Good Luck! :)
i watched just Наруто on Netflix but Ты can also watch it on theier website naruto.com if it doesnt come up then go to Наруто shippuden.com then on the bottom there is a link/picture that will bring Ты to it, или Ты can watch it on Vizanime.com, the only problem that it has cermercials
