Ultraseven is one of the darker Ultraman shows, and raising complex moral issues not usually brought up in Japanese superhero shows of the time.

Unlike the others, Ultraseven was not an alien hiding in a human, but an alien disguised as a human. He also had no need for a color timer because he had a life support tank and could fight well beyond the 3 minute time limit.

And Ultraseven is not a typical monster of the week show, as stated before. Often he was faced with hard choices, one of them saved the Earth but left him disgraced for a few years because it was save the Earth or save an alien race.

One problem with the set though. Episode 12 was very controversial in Japan (getting banned), and will probably not be in the set as a result.
