Have people not realized yet that streaming is good for genre shows?
		
		
	 
Long ago.  There's a lot of great genre stuff streaming - and on cable, for that matter.
It's a pity that STD looks so lame next to what other writers and producers have done there with the freedom.
TrekBBS is a self-selected group of enthusiasts.  Saying that a show called 
Star Trek is popular here is saying nothing about its overall acceptance.  It's certainly true that it's not nearly as popular as Trek was twenty years ago, as 
Corporal Captain pointed out.
During the late 80s and early 90s, TNG was more or less a mainstream hit.  Most people who like a show, though, just like that show - they're not looking to buy into a TV franchise or become part of a fannish cult, so when the show ends they don't necessarily follow the sequels.  Some sequels succeed on their own merits as entertainment (
Frasier) and some fail (every spinoff of
 Mary Tyler Moore or 
M*A*S*H).
DS9 launched with TNG numbers and quickly lost a good percentage of that audience, continuing to bleed viewers through its run.  The same was true of 
Voyager and 
Enterprise.  Viewers moved on after TNG.  Given that Trek toys were so profitable during the 80s and mid-90s* it's clear that a big percentage of the viewership were children  whose tastes changed dramatically as part of growing up.
*Real toys for children, not high-end collectible shit for older folks with credit cards.
