The Mysterious Cities of Gold, which reached legendary status in French Canada (presumably because Robotech and Gundam were too violent for the state broadcaster, but...), after a second season in 2013, got a third in 2016-it will be available in North America (in French however) this very week.
This is a 80s half-educative cartoon, as it was back then. It's not the show of the century. Its for kids.
And it's awesome
