Maybe a psychological trap plot was a little too ambitious for these writers. They can’t keep the basics of the setting and characters straight. The whole “4-D chess” psychology thing may be beyond them. Needless to say how this psychology experiment was supposed to work is tough to understand. What were those researches going to do if no one had wandered in? What were they doing before random people wandered in? We also revisit the tropes involving women as 70s proto clickbait. Older guy with younger female assistant, and possible girlfriend for Garth. They obviously had a “sex sells” mindset with female guest stars, but they could only go so far, so they needed something to draw the attention to, such as good sci-fi.
