This was a well written episode; the dialog and behavior of the characters was believable under the conditions of the story. Good acting, the presentation evoked thought; this type of contact seems to be the most likely considering the light speed barrier to space travel. Interesting science fiction story. Well worth watching.
The show was canceled a year before I was born and I watched re-runs every Sunday afternoon. This show along with The Twilight Zone and Alfred Hitchcock Presents planted the science fiction bug in my mind and after 1000's of books and movies I still love this show.
