Star Trek, as is the case with anything else that comes from Kingdom of Hollywood, only moves forward if it makes a profit or if those who produce it believe there will be profit to be made from it if they continue with it or if they dust it off and revive it if it has been sitting on the shelf for a while.
I don't feel that TPTB do enough homework. They latch onto a current trend, such as the action-adventure film, but they fail to take into consideration that they need balance, especially with a property like Star Trek. Plenty of the fan base, and even general audience members who go to theaters to see sci-fi films, want something with more depth and substance than the pew-pew.
This has also been a problem with Trek novels. You can't take a generic, same-old, same-old action story, stick an overlay of Star Trek details onto it, and expect it to be respected by Trek fans who are looking for something thought-provoking and engaging. Mack Bolan and Star Trek are not going to mix well.
A Star Trek film can have a wide appeal, if it is well-written and if it has that balance. The action fans can get enough of what they're looking for most, but the sci-fi fans can get a high level of what they're seeking, too. It all comes down to how everything is blended together.
If you don't have the skilled writers necessary to achieve the balance and make the blending work correctly, you will not end up with a successful product. You may end up pleasing only one side....or neither, especially if the consensus of opinion is that what you have created never knew what it really wanted to be.
At this moment in time, I don't feel that the studios in Hollywood are hiring enough truly imaginative writers. There's too much recycling and trudging down the same old paths.
They can't reach an agreement with Pine and Hemsworth? Move on. Never feel locked in to something. The possibilities are endless.
We never got to see what happened after 'Turnabout Intruder'. Kirk was a person who had been split in half by the transporter, had lost Edith, had lost Sam and Aurelan, had mind-melded with Spock, had gone through all kinds of traumas, and had then had his personality forcibly transposed into Janice Lester's body. When you add it all up, there was a hell of a lot. What if Kirk simply needed a break for a while and a couple of weeks of shore leave were not enough to recharge his batteries?
What if they brought someone else in to captain the Enterprise for a while? Being that it's the Kelvin timeline, they could bring in Will Decker. With a strong story and a skilled actor, it could work very well.
It seems to me that the studios get themselves stuck in ruts and their tunnel vision doesn't allow them to see the way out....
