Now Star trek is commerial entertainment and needs viewers to sate advertisers and their dollars. So generally, you need to appeal to a wide base and not just Trekkers.

At what point did Star Trek as a franchise lose the masses? It certainly was a safe enough bet that Paramount decided to launch an entire network on it's back. At some point after that, it lost those masses. Both in film and TV.

I recall some of the arguments being that it got too lost in it's own techno-babble and geekiness and it no longer was relatable to average viewers.

Where do you see it losing the millions? And this is not necessarily a question of when did YOU not like it.
