When TNG first started they were worried about having too many references or mentions of the old show, because they wanted TNG to stand alone as its own show.
Any new series or movie could be in the prime universe without really having tied or weighted down.
It would just be something new.
But it wouldn't really be new and no matter how hard they tried, they would invariably make a misstep in regards to background that would conflict with one of the already existing series. Then the fans would be storming the proverbial castle about how they weren't doing their research and how could they get something so simple wrong.
All you have to do is take a gander at this very board while Enterprise
was on the air.
I was here when enterprise was on and i remeber it being pretty split between "gushers and bashers"
