Star Wars does retcon and contradict itself . Like Princess Leia saying she could remember her mother's face, although she was infant when her mother died.
Or the rebels celebrating across the galaxy after the empire falls, in the last movie, then enters TFA, and everything starts all over again.
But for me, what makes up for it is the amount of detail in its world building. You know the people work and trade for a living. You even have crazy things like moisture farming businesses for money.
People go to bars, sell their vehicles for fast cash, smuggle things, gamble. People speak different languages. Droids have their own language we cant understand but the characters can.
Star Trek couldn't make up its mind--military or not, money or not, conflict amongst humans or not etc. That indecisiveness is what makes it so awkward at times. If it had a richer background, it could be easier to forgive.
SW even covered little details that didn't seem to matter at first, that the prequels ended up explaining.
Vader had a damaged body in a special suit he needed to stay alive in, even though this wasn't explained before they showed the prequels. Luke being raised by an aunt and uncle. The Emperor that controlled everything but we didn't really see him until the last movie.
It's two different types of franchises for sure. It's a fantasy world, but it has more rich details in it.
