I'm about to watch Naruto for the first time, so everything. I watched Classic on Netflix and when Shippuden appeared on Netflix I watched all the episodes except most of the filler episodes. But there are hundreds more to come, but Netflix doesn't go any further, it only goes until Season 10 on Netflix.
So you know ways I can continue to watch Naruto Shippuden in GERMAN! LEGAL AND OHME MUCH ADVERTISING! So not that every 5 minutes commercials turn on!
Amazon Prime (fee-based)
Crunchyroll (gersub / advertising> unless you get premium.)
TV Now (only up to episode 423)
On Tvknow you can watch until season 21 otherwise with subtitles on Crunchyroll completely
TV Now to follow 423, otherwise you just have to get Blu ray or DVD to watch everything in German.
Watched is an app, after downloading enter Hulu.to in the URL bar and is btw free and luckily I'm not the only one who sees Naruto for the first time lul
And of course without ads
Crunchyroll (advertising or premium)
