The episode is notable for the background family knowledge we learn about Kirk and some biological information about Vulcan physiology. The other episode is from the second season and is the first to feature Walter Koenig as Ensign Pavel Chekov. Both episodes feature alien life forms unlike anything the crew of the Enterprise had ever encountered on their mission. Played here by Glenn Corbett, the story concludes that the companion, a entity that saved Cochrane's life 150 years ago, has made Cochrane young again so in hindsight, the episode and film can fudge the obvious differences between the actor's features through this anecdote. The Dolby Digital 5.1 Surround is ambient and clear.
Menus are standard interactive stills and are easy to navigate.
Star Trek Collectors should be happy with these new releases and the upcoming ones as well.
