That's a matter of taste.
Personally, I think the dangers of serialization (whether in film
or on TV) is in the overarching plot becoming snarled around itself and ending up being a confusing mess, as the writers try to escalate things to top previous highs. I've seen too many good franchises go south because their serialization meant events just got sillier and sillier, or characters started acting out-of-character, or whatever.
Star Wars hasn't avoided that.
I think one of the things
Trek has got over Star Wars is that the stories are episodic and don't carry baggage over from previous stories.
Which isn't the same as avoiding
continuity. Trek, by and large, has often managed the tricky balancing act of trying to maintain and build continuity,
without becoming heavily serialized. For all the kvetching about the 'reset button' or whatever the truth is that the reason Trek and it's characters have got such a rich history is because people paid attention and built and built and built, fleshing it out.
The three modern Trek movies maintain this: an episodic feel, but with character development. Nothing wrong with that.
