allow me to explain why you are wrong.
1. Star Trek .. is a franchise? There is only one 'trek, only one captain - KIRK. TOS is the only 'trek which is watchable, once you take away the miniskirts, plastic bag monsters, facial putty makeup, bleeping lights and that classic theme tune, you got nothing left. "Serious" and Scifi dont normally go well together.
2. again . what exactly are we talking about? The film called Star Wars, or .. whatever those abomination are, that came afterwards?
Here’s how the very first Star Wars retcon went down.

it wasn't even called "A New Hope", or f* Episode IV. It was just "Star Wars".
Star Wars 1 & 2 are great films, SW3 is ok and a decent ending to the trilogy. SW 4/5/6 are possibly the worst films ever made, SW 7/8/9 are modern trash for ADHD kids.
Star Trek is only good when it's bad. TNG was fun for the first few episodes, and
then some of us realized how much of a nerdfest it was. Nothing else was even remotely watchable after that.
