The episode was interesting, telling the story of John-Boy's first time taking a girl to the movies and getting the surprise of his life. In his words, by way of the opening narration, "what happened was more astonishing to me than anything I could have imagined if I tried to write a story about such an innocent pleasure."
As the episode went along, what got to be more and more irritating was Sissy showing her lack of acting experience, or perhaps coaching, given that this was her first (or near first) on-screen appearance. She essentially just yelled her lines out in a very amateurish way. Based on this, it's a wonder she ever got another acting job.
