Another show that had it come out in the 80s would likely have got some European co-production money behind it and would have aired on the BBC. Classy Madhouse/Telecom co-production for NHK about a school field trip that goes badly wrong, leaving a group school children stuck on an uninhabited planet. One of those shows that there is an audience for, but it’s a TV audience rather than a DVD audience. And I’m certain US TV execs aren’t seeing this as being the sort of thing kids would watch (even though they probably would). If Erin is a success on Crunchyroll, it might be worth looking at similar NHK shows from the last ten years like this for streaming too.
