It wasn't exactly Star Trek -- well, the Star Trek episode with the space hippies was almost as bad -- but it was fun. What kid in the 1960s didn't want to be lost in space with the Robinsons?
Whatever you were interested in, there was someone for you on Lost in Space. Kids liked Billy Mumy, a busy child star with previous roles on The Twilight Zone and Village of the Giants (and later on Bless the Beasts and Children). Not only because he was cute, and knew it, getting teen idol attention at the age of twelve -- but because his character, Will Robinson, was bright and resourceful, a respected crew member, never told "you're just a kid" or "wait here where it's safe."
And Dr. Smith (Jonathan Harris), an accidental stowaway who provided comic relief. He was a big kid, an unrestrained id, gluttonous, lazy, cowardly, incompetent -- and flamboyantly feminine. The unabashed friendship between a young boy and an older man assumed to be gay was quite progressive in an era where gay men were often accused of being pedophiles.
Adults liked John Robinson, the patriarch of the family (Guy Williams), who also didn't seem much interested in girls. He had a wife, Maureen (June Lockhart), but they behaved like colleagues, with few moments of tenderness and none of intimacy. Guy Williams had previously starred in several buddy-bonding projects, including Zorro (1957-59) and Damon and Pythias (1962).
Teens liked Don West (Mark Goddard), the resolute, non-nonsense pilot (previously seen in The Monkey's Uncle with Tommy Kirk). Since the spaceship was crashed through most of the series, he didn't have a lot to do, and we didn't find out much about him except that he was dreamy, and not interested in girls. In early episodes, he had a romantic involvement with the older Robinson daughter, Judy (Marta Kristen), but soon it was dropped and forgotten about.
Unfortunately, the female crewmembers had even less to do than Don West. Maureen was a respected biochemist, but she was relegated to cooking and saying "Be careful." Judy helped her mother cook. The youngest daughter, Penny (Angela Cartwright, previously of Make Room for Daddy), had a few adventures, mostly involving adopting weird alien animals.
There was a bit of buddy-bonding, as in the episode "The Challenge" (1966), when Kurt Russell guest stars as an alien warrior. There was an occasional shot of a muscular alien. But the main draw for gay kids was the boy adventurer and his flamboyant pal.
