It wasn't too many months ago that I watched a sort of "reunion" show about Lost In Space. Had to be on a FTA satellite Ku channel as that would have been all that I was viewing at the time. All the stars were describing their roles in making the show and all the behind the scene details. It was a good show on the reflection of the series.
The series is an icon of classical TV! I assume that it ranks right up with Star Trek (the original series). Personally, I am more of a Star Trek fan, but this was definitely a "must watch" program.
