We know. It did spawn a fantastic series of books and other products though (like in them, Han Solo & Leia got married, had kids, who became jedis - it was a whole freaking universe that people created based on the original triology!), before George Lucas came back in and ruined it, and then Disney bought the franchise and flat-out crapped into its corpse (even so, those movies have their moments too, yet are so obvious cash-grabs that it is hard to ignore the bad in order to see the good).

The thing to remember is that the original Star Treks - TOS & especially TNG - were so "fantastical" and not relatable b/c they had basically eliminated poverty, and for the most part people got along quite nicely. They CHOSE to work, out of the spirit of adventure, b/c they were just that awesome. (Later, DS9 added terrorism and such, but it was hard to follow that show at the time b/c if you ever missed even one episode, then you had no clue what was going on in the next one - this was a different TV technology than today when you can guarantee watching them in sequence, without a VCR and your family members not taping over the show, grrr...:-P).

Whereas in Star Wars, there was literal fucking slavery, and politics and such - like even though technology was so advanced that literally nobody ever had to work ever again, they still forced people to, just for the sake of the cruelty of making that happen... Racist Jar Jar aside, the prequels tried to show more of that, like Naboo was being attacked, yet hardly anyone in the Senate fucking gave one single, tiniest crap about any of that (sound familiar?).

TLDR: Star Wars was more relatable than Star Trek, to many people, b/c it had more greed, power dynamics, fighting, broken people, just MOAR of the evil that pervades our world - and not just from the outside, from "them", but from the inside too, from "us".
