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