Making another TNG/Voyager-type show is instantly going to run into the problem of how to make it distinct from those two shows without causing the critics to immediately call "seen it all before". And yeah, it might be tempting to say that critics aren't fans, that they don't get it, and we shouldn't listen to anything they say - but casual audiences usually do listen to what they say, and the last time that critics outright bashed a Trek-related work, it was Nemesis. And we all know how that turned out.
Besides, saying a franchise is supposed be X or Y is a pretty narrow-minded view to take. Just to name one other example, James Bond has managed to make it work both as a gritty spy drama and a high-camp adventure series over the years. Sure, there have been times when they've gone too far in one direction or the other and ended up alienating audiences (i.e. Licence to Kill in the case of the serious style, and Die Another Day in the more over-the-top style), but with good enough storytelling, audiences will often let you get away with a lot.
They could make it more like DS9.
That series had some "dark" episodes but those in charge also had the good tste to throw in some lighter episodes here and there and DS9 was never so dull and boring as the current series and most of everything we have to watch on TV today.
DS9 ha the good fortune to have great actors, great characters, great writers and producers who managed to come up with something interesting, exciting and entertaining. But I guess that such things are hard to find in this dystopic world.
I think that Star Trek must stand for what it is supposed to be and don't follow the dystopian trends we see right now.
As for critics, they always hold a finger in the air to feel where the wind blows. I know about a guy who obviously had been a good critic once but when punk rock got its big break in Europe at the end of the 70's, he started to trash all the bands he had written good reviews about before and started to hail punk rock as "the new fantastic thing", just to make it look that he was a part of "the new wave".
Some years passed and all of a sudden, the punk bands this critic had hailed as foreruners of something new and big were gone and the bands he once had praised but then started to trash were now hailed as "rock icons" and legends, especially when hard rock and heavy metal became popular again.
Exit critic! The fans of those old bands never forgave him for what he had written before and when he tried to save his face by starting praising them again, he was revealed as the hypocrite he was.
