I tried all the Tokusatsu during the explosion of the early 1990s, because i LOVE Robots, Martial ARts, and Super-Heroes. Well, SSSS Is the BEST of them all. Not much in Marial Arts, but this show soooo reminded me of ULTRAMAN, which i watched alot as a child of the 1970s.
The show was like Saved By The Bell mixed with Ultraman.
The uniqueness was in the fact that he didn't fight in the city where he might step on tiny humans...he found in the Cyber-world, where Viruses and bugs plagued the world's computer dependent society (and this was before the WWW, as far as i knew).
