It was the 60's the space race was on and the televisions were tuned to Lost In Space. The first season was in B&W and was quite adventurous and serious with some very good episodes and stories.
The second thing the show was broadcasted in color and as soon as that happened it went Hi camp. the majority of the family became supporting castes and Will, Dr. Smith and the Robot became the mainstay. Silly plots, horrible writing and even worse sets made season 2 almost unbearable.
Season 3 went back to some season 1 formula with mild camp and was much better than season 2. Sadly the damage had been done and the plug was pulled after only 3/4 of a season.
