I get it-- and, it is very likely that I will join the hate squad at some time. I am just likely too anesthetized by a generation or two of significantly low standards of entertainment and writing... And I wasn't really comparing Trek to Tolkien as art. Tolkien took 17 years to construct Middle Earth and The Lord of the Rings. It's serious high art. Trek is all over the place... It was a fan-base comparison.
I think you hit the nail right on the head-- I would love to see an extension of this world that is of equivalent depth, nuance and structure. But that is asking a lot. More than 99.99% of TV entertainment for sure.
Again; look at the multiple macerations of Dune.
I repeat-- i am not comparing levels of artistic merit; I am disgusted with just about everything Star Wars after Empire (but again, Star Wars is low-brow).
It is so incredibly rare to find a movie or series version that complements or compares with the text, when the novel/book is complex. LeCarre has been serialized reasonably well in Little Drummer Girl and The Night Manager but still nothing close to his novels. Philip K Dick has been successfully converted more than a few times, but having been a reader of his, I can sincerely state that he is an idea genius but not a great "writer." A read of his novels in the 21st century reveals it.
So yeah, I am a stupid wanna be fanboy for now... I will graciously apologize to the board when/if its sacrilegious stupidity penetrates my bulbous cranium.
