I prefer the 'fiction' part of science-fiction.
Well, all stories are fiction, unless they are inspired or based on true event. The problem is that maybe some people here don't understand what is the different between fantasy and Fiction. IF somebody think that it is better than Star Trek embrace "Fantasy" route rather than Science things, then what is the different between Star Trek and Star Wars or even the Guardian of Galaxy?
If Star Trek still want to become a Sci-Fi, they should stay as Sci-Fi. They should back to their roots. The writers should use our today reality and science as the basis of Star Trek background and material. They can't go back to TOS canon. Because TOS canon can't be considered as "right" anymore. Unless Star Trek set course to Fantasy Genre, we should forget about TOS and TNG canon; and embrace a new reality based on today technology, science, and reality. Or somebody want to see Gandalf in a Star Ship and go no men has gone before?
Edit, Addition :
Sci-Fi doesn't mean that you have to see some technobabble in the story. What sci-fi means is that you tell a story based on today reality, science, and technology, and expand it to become a forecast about what will happen in the future. TOS was a Sci-Fi. Because it based on the reality in 60' era, and expand it to become a forecast about what will happen in the future. But, it's no longer a sci-fi for today audience. If Star Trek still want to embrace TOS era canon and imagination, then Star Trek will be surely reroute into Fantasy Land. I dunno which is better. For me, the sci-if is better than the fantasy. Because we have already have Star Wars and Guardian of the Galaxy. So why not fill the Sci-Fi genre with Star Trek; which is originally is Sci-Fi.

So what will Sci-Fi Star Trek be seen if they decide to broadcast a new series again?
- Scrap TOS and TNG canon. Refresh the canon and background with today reality, science, and technology; expand it into a highly advanced but possible future of humanity. I don't mind they keep the characters and factions. But change the date and history, and implement a new idea of technology based on today highly advanced techno. People know that humanity still trapped in our planet until 21st century. So it will be laugh-able if Star Trek say that we have already have explore the universe before then.
- Make it looks more real. I don't say that they must take hard science story like Gravity or others. But make the tech that they use as more believe-able for today audience. People have different perceptive of Alien; they have different imagination of space, and they are more knowledge-able than the '60 and '80 thanks for the internet. So refresh them all. Make an imaginative future that humanity will face in our beloved Series. What will 21st century audience will see about their Earth and space in 23rd century? Or maybe 22nd century? A handheld tricoder that is no better than our 21st Iphone?
- Vulcan was so amazing back on TOS era. Because for '60 era audience, a human actor with Elven ear is already amazing and spectacular. But what about today audience? Will people who have seen 3D monstrous Alien will still believe and enjoy an actor with some mask and cosmetic ?
If Star Trek still can't get out of the old canon and their obsolete idea trap, don't call it Sci-Fi anymore. Call it Fantasy. The problem is, there are better fantasy in space out there. Like Star Wars and Guardian of Galaxy. And Star Trek's strong point was in it's sci-fi touch.
