The Original Series is my favorite show of the Trek franchise. I imprinted young when I developed a crush on Captain Kirk at eleven. At it's best it could be amazing, and featured scripts by science fiction talents such as Theodore Sturgeon and Harlan Ellison.

Both of these are First Season episodes, which featured many of the best Trek produced. "Arena" is fairly strong episode--with a clever twist. It was based on a classic science fiction story by Fredric Brown. But "The Alternate Factor" is the most incoherent episode in all of Trek and rivals the notorious "Spock's Brain" for stupidity. As a little girl though I did love that Lieutenant Charlene Masters ordered a guy around--not something you often saw in the original series. ( )
