Ep 27. The Alternative Factor

The episode titled "The Alternative Factor" is the twenty-seventh episode of the first season of the iconic science fiction television series Star Trek. It aired for the first time on March 30, 1967, and has since become a fan favorite among Trekkies.

The episode begins with the Enterprise on a routine mission to explore an uncharted planet. However, the crew soon discovers a strange phenomenon that is causing the planet to disappear and reappear at irregular intervals. After further investigation, they encounter a mysterious stranger named Lazarus, who claims to be in pursuit of a dangerous creature known as the "Eternal Enemy."

Lazarus is played by actor John Drew Barrymore, and the character is one of the most complex and enigmatic in the entire Star Trek franchise. He appears to be erratic and unstable, but he is also extremely intelligent and resourceful. The crew of the Enterprise is initially wary of him, but they soon realize that he may be their only hope of stopping the planet from being destroyed.

As the episode progresses, it becomes clear that there are actually two versions of Lazarus – one of them sane and coherent, the other unstable and dangerous. The two versions of Lazarus are played by Barrymore, who gives a masterful performance in his dual roles.

The plot of "The Alternative Factor" is full of suspense and intrigue, with plenty of twists and turns to keep viewers on the edge of their seats. There are several memorable scenes, including a tense showdown between the two versions of Lazarus and a thrilling sequence in which the Enterprise races against time to prevent the planet from being destroyed.

One of the strengths of "The Alternative Factor" is its exploration of complex themes such as duality, madness, and redemption. Through the character of Lazarus, the episode grapples with questions about what it means to be human, and whether it is ever possible to outrun one's past mistakes.

Another highlight of the episode is the strong performances of the cast, particularly William Shatner as Captain Kirk and Leonard Nimoy as Mr. Spock. Shatner brings his trademark charisma and energy to the role, while Nimoy imbues Spock with his usual understated intelligence and dry wit.

Overall, "The Alternative Factor" is a standout episode of Star Trek's first season, and a must-watch for fans of the series. It's an exciting, thought-provoking, and well-executed installment of one of the most beloved science fiction franchises of all time.
