Lost in Space lasted too long IMO. It's first season was good strong SciFi. Then it changed format and went to color. The format change was to compete with Batman (really, look it up... they went camp to get the Batman viewers hooked). As soon as they went to goofy camp humor in place of solid SciFi, it went in the toilet. I wish someone would reboot the series today and do it all serious. No talking carrot people, no space wizards, no giant robot then shrinking back to normal size with Will and Doctor Smith caught inside. And if you must make Doctor Smith a coward, make it an act. He really is brave and smart, he just plays cowardly to keep the family from discovering that he is responsible for their being lost.
