On TV for 4 seasons, from 1964 to 1968, (a spin-off from the 1961 movie of the same name) I grew up with this Television classic. Amazing special effects, but sometimes silly stories, still made for a classic show that I wanted to watch each and every time it was on television.
Every kid loved the show and were amazed by the special-effects. For many of us, the transition to colour in the episodes happened at the same time that our families purchased a colour TV!
