I picked Spacial Anomaly. What I really like is when there’s a problem, and they apply Treknobabble™ to their existing systems, modifying them on the fly, and address the problem, and fly away. Its best if they can do it without hand-holding, hand wringing, tearful growth.
Come to think of it, I like some character development, but only if:
Worf learns how to be a Real™ Klingon, while still addressing a thorny subject outside of the Real Klingon idiom.
Quark learns how to channel his Ferengi greed for the greater good and greed of all people. I seem to recall him criticizing Brunt when he connived to become Nagus – but I can only paraphrase:
Ishka: Well, Brunt will be a great Nagus, he’ll bring down the Ferengi Alliance, just to enrich himself, just like a Ferengi ought to.
Quark: No Mom. A Nagus is supposed to be bigger than that. A Nagus’s greed is supposed transcend his own for the greater greed of the entire alliance.
Iska should have said, “You’ve spent too much time around hoo-mans, Quark”
I just don’t care much for Data gets a girlfriend or Picard drinks wine and calls his older brother a bully or Riker fights his father, and finds out his father cheats to beat him.
