A race that embraces their sexuality and has no trouble expressing it, is not a bad thing to portray especially against the so-far very buttoned up members of Starfleet, but their some of the opening scenes are borderline softcore pornography.
If "Justice" is "borderline softcore pornography," that's got to be an incredibly wide borderline. You've got people in skimpy outfits hugging the away team, jogging, dancing, and playing instruments, and there's one guy getting a massage from a couple of women. That's no racier than a typical Baywatch episode. I guess such scenes could be considered softcore if the participants were actually nude, but they're not. Standards were looser in 1987 than they'd been 20 years before, but nothing anywhere near softcore would have been permitted on commercial television, even in syndication.
However, as with many episodes at this early stage, there's just something not quite right, that maybe another draft would have caught.
In fact, the problem is that it had too many drafts. It was actually the first script written after "Farpoint" but got delayed due to multiple massive rewrites. I read an interview with John D.F. Black in a Starlog issue where he talked about his plans for this episode while it was still in development, and I was startled by how profoundly the story had mutated when I finally saw it onscreen. Memory Alpha summarizes it thusly:
"In Black's treatment, the colony of Llarof installed punishment zones to fight anarchy; however, the zones are now enforced to abide the law, but for only those who are deemed not immune to them. An Enterprise-D security guard, Officer Tenson, protecting two children while on shore leave, happens upon a crime scene, and is shot dead by the policeman Siwel, who is also killed by his partner Oitap on the spot, for misinterpreting his duty. In his first draft, Picard decides not to help the rebels led by Reneg who fight against this system of council member Trebor. Finally, it turns out the rebels install a similarly totalitarian regime when they gain power. In the second draft, the rebel leader, called Reneg is put on trial and executed for treason. Picard muses on the topic of people having their right to decide their own justice without interference."
So Black developed a dark, thoughtful story examining challenging ethical questions, but it was massively rewritten and changed into something virtually unrecognizable. For whatever reason, Roddenberry looked at this tense dystopian story and decided to make it the platform for his indulgence of all the sexy stuff he wasn't allowed to put into TOS. Presumably that's why Black chose to take his name off the script and use the "Ralph Wills" pseudonym.
I sense a pattern in the proper nouns there. Llarof is "for all" backward, as in "justice for all." Reneg inverts "Gene R," Trebor is obviously "Robert" (as in Justman?), and Siwel is "Lewis" (dunno). Oitap is "patio" backward, so maybe that's where Black did his writing. Interesting that he has "Reneg" at odds with "Trebor" and ending up executed. Some behind-the-scenes commentary there?
