There are a lot of things to consider in Nexus, and the writers threw a lot at the viewer in the form of Lethe, the Visitors, Prometheus children, and whatnot.
Didn't they re-air it at like 2am and get better ratings?
they would probably be more concerned about 2016... the 50th anniversary of Ultraman. something big is coming, I can feel it. and I hope I will be able to make the trip to Ulfes that year.
