Besides having what is arguably the ugliest alien of all episodes, this one gives insight into the phrase, "I guess." This episode directly followed "The Anti-Matter Man," which also featured duplicates of Prof Robinson and Major West. In "Target Earth," we get duplicates of everyone except Will. The duplicate John and Don are always arguing. Funny, since the real men were usually good friends. Overall, a really fun episode, but with one of the most ridiculous situations in the series. At the beginning, Dr Smith separates the upper and lower parts of the Robot. The Robot's upper half remains suspended in mid air. Everyone aboard sees this-and nobody questions why the upper half doesn't fall to the floor! Amazing! I guess!
