This was an acceptably written episode; the dialog was kind of corny, the story was not compelling. Kind of hammy acting, the presentation evoked little emotion; it did not much matter to me if the general recovered or not. Not hard science fiction, but mildly interesting. There was no resolution to what the creature was, what it wanted, what it did to the general. cool looking monster, 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.
