I am now about a third of the way through Super-1. The basic premise is, it's a kung-fu "my style is stronger than your style!" show in sci-fi clothes. Ain't the worst so far, it's passable. The costume is okay, but the glove tassels are a bit much even for 1980. I think I'm into Oki Kazuya as a Rider. He might not have the panache of Kazami Shiro or Jo Shigeru, but he's got something.
Also, the theme songs continue to get worse with every show. I mean, I'm not asking for a masterpiece, just a little bit of effort. Fortunately I'm told it soon gets better.
