I didn´t catch OP until 84 during a rerun. I saw NSNA first, and my initial reaction was that it was a lot weaker than both NSNA and the previous Moore film, FYEO. I still find it weaker than those two, but not by as much as before. Its main problem is that its silliness is so damn silly, with no redeeming qualities. The characters aren´t that great, either. The villains are fine, I guess.
The pts is great, though and there is some fantastic stunt work in several scenes. I was intrigued by the title when I first learned of it. Was it perhaps the name of a mysterious and sinister organization? That was how my teenage mind worked.
