I think the worst sign was that they said they weren't going to care about
continuity.
I understood the special effects and props were going to be better than
the original series. I was prepared to accept "dramatic license" on those,
as they said they were going to do. I agreed with the reasons.
What I didn't like was the idea that they weren't going to integrate into the
Trek continuity. We could have had a story centered around how a little
planet with backwards-technology could grow to run the UFP in a few
centuries. We could have had the UESPA ships with their lasers.
Instead, we got something else.
A number of fans complained that the Powers-That-Be took the model of
the Akira-class starships, flipped it upside down, and announced that would
be the ship model. It was lazy, and produced scaling problems and gave
us an Enterprise with things present on the model that were not present
in the starship.
I had the same problem with Enterprise as I did with Voyager- I had to hunt
down the episodes, and they didn't re-run them at flexible times. I was at
work or leaving for work whenever they ran.
