These days we’re used to the `season finale` in which various plots merge together and its all very dramatic. Back in the 70s tv wasn’t really like that- the only people who had conversations about story arcs were tv producers. Most episodic tv was made to be shown in any order so that whatever the peril everyone was fine by the end of the episode in time for some bantz and a jokey freeze frame. It does become a bit of a problem with a series like this. Consider- the half Moon has been juddering about the Galaxy now for 2,409 days according to the opening voiceover. In all that time and given all the adventures we’ve seen the place still looks spotless (we never see a cleaner), all the damage is repaired (where do they get the spare wall sections?) and the uniforms remain pristine (we never know where the laundry is). More importantly the psychological status of all concerned seems to be no more stressed than after a full day at the office. Sure someone occasionally has a meltdown (as happens in this episode) but it never lasts and only serves a plot point. It reminds me of the Star Trek Next Generation episode where someone changed into a different life form but three days later they were fine and back on duty! Really? So as we reach the end of our lunar trek it seems appropriate to point out how much better a series this would have been had the strains taken their toll both on the structures and the personnel. I’d love to have seen a stretch of corridor with a patchwork repair noticeable on it. Or some people no longer in uniform. Or Helena perhaps engaging in some counselling that involves talking about mental health rather than using some medical device that heals instantly. The aesthetic of the series is too clean in every respect.
