In the original series, Lost in Space, I thought it was interesting that the Robinson’s land on an ALIEN planet. They run into a guy who tells them that there are ALIEN life forms all over the planet.
Every time Will tells the family he saw a new alien, they all think he’s crazy and accuse him of making up stories.
Then, the Robinsons kill the alien life forms.
I don’t remember the plots now.
That is an interesting observation though.
I used to think it was so dumb to plan to kill the alien right off, but seeing how lame humanity has become, it’s beginning make total sense to me now.
