Memorable episode, thanks to John Abbot
22 September 2010 | by (North West England) – See all my reviews

Guest star John Abbot as Sesmar, clearly a naturally talented actor, makes this very enjoyable to watch. Here he plays an arrogant mad-genius scientist and naturally he has to have a monster which gets out of control! Not every season two episode is a classic, but I think the season is a bit underrated. We do have some good episodes to enjoy, and this is one of them.

Emotionless Sesmar needs something the human Robinsons have, namely their emotions and Dr Smith is only too eager to oblige doing the dirty work in helping to turn the Robinsons into mindless zombies.

Here we get to see Don and Smith having to co-operate with each other in order to get out of their predicament. It's also great to see Professor Robinson and the children in a lazy frame of mind rather than being so industrious all of the time.

OK, so the resolution to the story may be a little absurd, but overall it's a lot of fun. Particularly, watching Dr Smith being shouted down by Sesmar and the bickering with Don, which is quite amusing here.

Sesmar's android Raddion is great too. You've just got to like the reel-to-reel tape drive mounted on his abdomen and Sesmar's proclamation that Raddion's lifespan is practically eternal. He's obviously never worked with computer tapes that have shed their oxide or become stretched or chewed-up then! The whole thing's just classic 60's sci-fi, highly entertaining.
