Incredible that you can get a funded research fellowship to chat about opinions of Star Trek.
I need one of those.
But in response to your question, I can only tell you what my impressions are about
this particular community. And I don't necessarily know if you will get the same answers if you go to Startrek.com, which tends to attract more casual fans who might be more here today/gone tomorrow in terms of their community affiliation there.
On this board, I would definitely say that
Enterprise is the most disliked of the Trek shows with
Voyager in 4th place right in front of it.
Deep Space Nine and
Star Trek (the original series) are probably the most popular, with
The Next Generation occupying the middle position of the bunch.
I don't think that this board is representative of all Star Trek fans, however. If you go to a Star Trek Convention, for example, I think that you will find that TNG is alot more popular than it is here.
I don't know what that is...but that is the way things have turned out here.
And yeah, I do think that alot of hard-core
Enterprise fans were 'new' fans who had not seen the other shows (or very little in passing) before watching
Enterprise. Certainly not all
Enterprise fans are in that boat...but I did notice a disproportionately large number of the really hard-core posters in the
Enterprise forum would eventually reveal that they were new fans to Star Trek with
Enterprise.
You might get different opinions from others...but that is the way things sit from my perspective of almost 7 years on this board.
