This series was actually made by Tsuburaya-Production, which is known as the creator of entire ULTRAMAN series. But Ultraman series was more for Kids, and they decided to make new series which could also attract mature audience.it is from end 60's and for TV series, so of course special effects look cheesy, but entire series has its own atmosphere. It is very unfortunate that well made series like this, has almost no chance to be released on DVD outside of japan even there are tons of trash coming on DVDs. Actually, In Japan they released the DVDs of this series,but no subtitles at all, and expensive. so far this series was Aired just once in Germany in 1971 ,but not entire 26episodes,but 13 episodes.If they release entire series on DVD with subtitle now, that would be very interesting for many audiences in Europe... by the way, episode 24 is now BANNED in japan,so even Japanese DVD doesn't have this episode.(this episode is about Schizophrenia) Well if its not suitable for Japanese audience, but maybe European audience might be more open for hat Theme,,,so please release DVD in Europe!!
