c amon guy some previous reviewer have nearly write a novel comment on this episode . it just an old 60 tv show . this episode of star trek be notable because of the most serious babe ( yeoman barrow ) ever use on star trek and the fact that it be film in a real outdoor location . unlike the tng and voyager series which be totally confine to sound stage . this use of an outdoor location ( and babe ) give proper depth and an almost film like quality to a quite ordinary episode of this now dated and very familiar show . except a few notable exception i. e the city on the edge of forever and assignment earth and tomorrow be yesterday the old series of star trek need to be seriously moth balled and put out of it bore misery . half a dozen good episode from 79 be quite a poor batting average . this be typical of the boring stuff gene roddenberry produce back then actually and contrary to popular belief where some people worship the ground he walk on and he actually make a lot of rubbish . he doesn not deserve to be speak of in the same breath a irwin allen for example . just look at the set of the bridge of the enterprise from a modern point of view . they use wobbly plywood for the floor and cafeteria chair with plastic back and cheap cardboard above the instrument panel . you can clearly see the fold in the paper . every expense spar or what .
