OK, my turn!
having to log in every time I visit the site.... annoying. It wasn't that way before.
The mobile apps taking a day and a half to play videos... annoying. It wasn't that way before.
Having to tell the apps that you want to play simuldub episodes in English even though there is no other option... annoying.
having a window pop up in the PS4 app telling you that the next episode starts In 50 (49...48...47...) seconds, which, go figure, is the exact amount of time left in the video... annoying. Netflix says screw it and goes to the next video like 15 seconds after the credits start rolling.
