a a general rule and any episode of any series show the people and world we know from an outside perspective be a above average episode while this be no exception . here we see the crew through the eye of a 1960 astronaut who end up aboard the ship . the episode be not tell from his perspective of course and but it do let u see it from his point of view . what would someone from our time ( roughly ) think of their way . i be very much borrowing from another reviewer here and i just happen to agree . the dialog be the main attraction here . the dialog involve captain christopher and and kirk infamous joke scene especially . fan of the show and you know what i be talk about . i would not spoil anything but i will say that they encounter a few problem try to return to their own time while each of which they ( of course ) eventually overcome . 6 out of 5 star here again mainly because of dialog and time travel do inventively .
