Well how many times can you beat a dead horse...? The dilemma is they're going to wring out as much of they can doing all the same things all over again in a reboot to try to figure out something original which bounds to violate canon. I see why because they are stuck having to bank on the built-in fanbase and audience boxed-in with characters they know to get them to watch hence why they're afraid of doing anything new that takes place in the future with new characters. The problem with the Kelvin timeline was Jar Jar Abrams was involved. Everything he did was superficial and was only about making something that was loved by fans into something that had the only goal to be something he can claim as his. And the primary way to do that is by changing everything that everyone knew before. That's not a fan move. That's an ego move. He wasn't even a fan of Star Trek but he did that with Star Wars too which he said he was a fan.
They should do it all if they're so worried about doing anything completely new. The only thing I saw that could've been interesting with the Kelvin timeline was the different what if scenarios that were possible. But JJ Abrams didn't do that. All he did was change what everyone was a fan of. I was looking for something like what if the Dominion or the Borg invaded the TOS timeline first. That kind of mix. Generally what Star Trek does is a lot is plots where they're trying to save the timeline and restore it to before. So to keep up with that tradition is a whole series of movies dealing with that... mixing eras and genres recasting familiar characters along with new ones and if it's popular they can do something entirely new and don't have to rely on the past and move on.
JJ Abrams poisoned Star Trek with his kind of thinking that led to what happened to Alex Kurtzman's Star Trek. That was an attempt to use something that had a huge fanbase in popular culture and turn it into a social engineering tool for just specific interests. That's why they want to claim a stake in all fantasy because that's the only way they can do it and impose their beliefs in a popular genre. It gives credibility to the charge they're trying to indoctrinate people.
