The CBS Action television channel is showing the original Star Trek series. Next Wednesday 18th at 18.00 they are scheduled to show the episode "City on the Edge of Forever" (from 1967).
It's is exceptional drama of the highest quality and is worth watching by anyone who appreciates good television. There's no monsters, no battle scenes, no alien planets - it's set on Earth, just a very human story, and one which you won't forget. You don't need to be a Star Trek fan to appreciate it and you don't need to have ever seen anything of Star Trek.
Excellent intelligent story. The acting is outstanding, and is the best thing that either William Shatner or Joan Collins (guest appearance) has ever done by a long way.
IMDB rating of 9.3 is justified. It's possibly the best US televison drama of the 1960s.
