I'll watch a Stop at Willoughby.
Each year my daughter and I create a village with lighted houses and figures under our Christmas tree and we call the village "Willoughby" in honor of this episode.
I too love the "Howling Man" and, of course, "Twenty-two." Thirdfrom the Sun is another good one with a classic TZ twist.
"Twenty two" was a good one as well. So was "The Invaders."
You know the whole idea behind "Life on Mars" happens in a nutshell in "Stop at Willoughby." Each and every episode has a wonderful idea. I should make time to watch the next seasons.
