Since others have fully covered the Q portion of your comment I came to say that that cool saucer separation that’s so bad ass happens like 3 times max!
I get that maybe it’s “expensive” or awkward to write or something from the production standpoint that makes it underused, but seriously, is it “expensive” in-universe?! Because they spread that shit out more sparingly than me buying pine nuts!
Other show reference alert: it’s a lot like on Deep Space 9 how rarely Odo changes. If I had that fucking power I wouldn’t hold back! Let’s see, can I squeeze any more complaints in? I never understood the premise on Bewitched that Darren & Sam wouldn’t want to use her powers to make things better constantly! Ok I’m done. For now.
