Okay people, it seems like a lot of you don't yet realize how technology works. First off, season 10 has just recently been launched, and not all episodes have been aired on nickelodeon. Once they air on nick, they are added to amazon. Its basically a preorder. Second, most of you that gave bad reviews complaining about this, have had amazon's helpful reply's. One I saw even had amazon bend over backwards for them, and they changed to a positive review. That is what the rest of you should be doing. Amazon has done nothing wrong and neither has nickelodeon, just because you preordered a season online, doesn't mean you get the episodes before the rest of the world. Fix your reviews.
Edit: this season(10) will consist of 11-1/2 hour episodes. Take that into consideration before you purchase. Nearly every season before this consisted of 26 episodes. As of right now there are 2-1/2 hour episodes to be released.
