This could have been one of the best episodes of the series but unfortunately Dr. Smith and is hammed up acting bring down the entire episode and its too bad. The idea of using the boys to bring the two species together and examine their differences could have played for some interesting cultural exploration. Instead Dr. Smith dominates the plot spouting long streams of dialog that bring the episode down because they don't advance the plot, they only give Dr. Smith some air time. In the end, John Robinson spouts of a lot of exposition about who they are and why they left. I suspect a scene or two was cut to make way for Dr. Smith and his dialog that would have been crucial for the episode. Obviously we can't remove our Dr. Smith moments.
