I never saw Spectreman when it aired sporadically in the US in about 1978. I wish I had, since I would like it more than I do now. I enjoy it, but it doesn't have the impact of Ultraman or Johnny Sokko had on me. it is a fun show. I like that they used stop-motion for at least one of Spectreman's monstrous foes.
the dialog between Dr. Gori and Karis is usually pretty funny, thanks to Mel Welles.
