Personally I choose to enjoy the wealth that the ST universe has to offer. Everything has a high water mark and it may be that time has passed by what we all knew as Star Trek -- at least in that form / format . It may well need to change with the times to find an audience. Unfortunately, ST may never enjoy the popularity it once had.
Agreed. I think if Star Trek is to appeal again in the way it once did, it will have to fundamentally change its approach, tone, and writing style. People will say "that's not Star Trek!" but they said that about TNG, too. The TNG era changed pretty fundamentally what the TOS era was all about, and that could happen again. The mistake that was made was not even making too many trips to that well, but making them long after the rest of the entertainment industry had moved on. Enterprise was competing with contemporaries like Battlestar Galactica that were redefining what Sci-fi could do and be about while Archer and co repeated TNG stories with different named aliens.
New Star Trek must appeal to the audience in front of it today, not the audience of Encounter at Farpoint. A 5th TNG movie, or another series from the same mold as VOY or ENT would not be a success, any more than the TOS movies would still be making money if they'd carried on any further into the cast's dotage. Network executives are ridiculed for wanting things that are 'fresh and edgy' but fundamentally they have a point - if a new Star Trek TV show is to work, it has to work in the fall lineup for 2016, not 1986.
