What are the biggest red flags when talking with a Trek "fan"?

I've taken to the term 3rd-wave Trek for the 2010s-present shows to identify the stylistic differences in production compared to shows made in the 80s-90s or 60s.

Each era is molded by the media conventions of it's time. And there I go reinventing Marshal McLuhan again: "the medium is the message"

I don’t mind the Kelvin films. Karl Urban as Bones makes it all worth while.

They’re just popcorn flicks. Watch or don’t watch and it’s not like the Star Trek Universe is altered in any way. (Also, those movies are better than everything after Wrath of Khan, movie-wise)

Both panels are acceptable and objectively correct.

You're fooling yourself if you don't want to see the sharp decrease in quality post DS9. The best Trek series of the last 25 years is Orville ffs
