||This was a half-decent story, but suffers from a major plot hole. Why was Dr Adams messing with people's heads? Was he actually trying to help people in some twisted way, or was he after power, or simply getting a kick out of it? Somehow, not knowing that rather ruined the effect. We saw the first mind meld here, and it certainly looked very alien when first seen, so exactly the effect they wanted. The upgraded planet with its ring system was nicely done, and much better than simply re-using the Delta Vega backdrop (which seems lazy even by 1969 standards). Overall, flawed, but not too bad.
