Season One Ends With A Winner
15 February 2015 | by See all my reviews

An alien spirit, Canto, possesses John Robinson.

When seen in my 1970s childhood this episode scared the hell out of me. I don't have the same reaction as an adult today...but I still love Follow The Leader.

The voice artist for Canto - Gregory Morton - would have to be the most under-rated and under-used voice artist in Hollywood history!

I can think of many 1960s sci-fi TV hours that would have been given a lift if Morton was employed.

An so ends the 29 episode season one. The first 17 episodes were mostly outstanding, the ones that came after were mostly good, and just two stinkers (The Oasis, A Change Of Space) in the whole 29 episode run. Not bad at all.
