Maybe people just don't respond to some things. Lost in Space is best known as the goofy old show where a mincing pedophile would insult a robot. The movie is about space spiders, time bubbles and something vague about families.
Star Trek is best known as the show where Kirk seduces women, Spock is smart and they fight bad guys in space. The movie reproduced that and told a decent story as well.
"When Dr. Smith met Mr. Spock"
That would've made a great title of an episode for A Lost In Space crossover with TOS.
