One thing the various Trek productions have proved over the years is that saying you’re going to make a Trek film or TV series in a particular sort of way or for a particular type of audience does not necessarily mean that you have the slightest clue how to actually do it.
Oddly, neither Enterprise nor Nemesis were made for 'hardcore fans'. In fact, the production teams for both of those projects went out of their way to say that it was to capture a 'new' audience , even if it meant alienating some of the 'old fan base'.
This is true. It's also true that the fact that two very different productions - Abrams' film and "Enterprise" - have made similar choices in several regards is in large part because the alternatives are not reasonable.
To cater to the hard-core Trek fan base, small as it's become, is to guarantee commercial failure. And to do it to the tune of 130 million dollars would be criminal irresponsibility where the stockholders of CBS and Paramount are concerned.
One might as well spend over 100 million dollars making a "Stargate SG-1" film or a similarly-budgeted film based on Ron Moore's "Battlestar Galactica" - they're both popular with a certain number of people, are reasonably well-regarded by lots of folks and are successful within limits that satisfy their studios and producers and networks, but no one has any reason to believe that an audience of sufficient size exists to make such a huge investment reasonable. And so, these days, with "Star Trek."
