It’s so bizarre to read this in the present, knowing how incredible TNG was, but I get it - the original crew WAS Star Trek to them.
The dedicated fans revived this series in syndication, well after it had gone off the air in 1969, and felt attached to the characters that they had obsessed over between then and the 1980s. Like modern fans, they thought that departure from what they knew would ruin it.
I wish I could go back in time and tell them that TNG is going to rock.
This is actually true though
I remain slightly miffed about how Dr Pulaski, one of the few characters that received any development in TNG S2, was so hated by some fans that it caused to Diane Muldur to swear off of Trek altogether.
She might not have entirely understood Data to begin with, but she did become better at that later on, a stark contrast to much of the rest of the Federation, which would still be arguing whether he, or his children had personhood, and is the only Starfleet Doctor in RetroTrek to actively take an interest in and engage with her patient’s cultures.
I can’t envision early Dr Crusher taking part in Worf’s Klingon tea ceremony, for example.
Still better than Star Wars fans, though. Same as it ever was
