This is a classic episode and explores the Vulcans first contact with humans. The interactions and dissent within Vulcan ranks is explored. Especially Mestral's desire to know more about and explore the Earth. From watching TV, inparticular I Love Lucy and westerns, to interactions with the people he is very curious.
Also it was nice to see T'Mir sell the idea for velcro to help Jack make it to college. Some might look at this as emotional, but I think it was simply practical. Payback for the help he and his mother, Maggie, provided to the shipwrecked Vulcans.
This is one of the best episodes because the story is told so well.
