I so get you about why Stamets mattered. He was a fun recurring guest character on Star Trek Online too and had lots of spoken dialogue with the usual “funny yet depressed” vibes.
What gets on my tits in a huge way are the outright ignoring of shit in lore.
I’m old enough that I still groan when I hear percolating returns of the “DAE KIRK KILLED OR FUCKED EVERYTHING THAT MOVED” ultra-Flanderization brainworms of decades past.
