I think what needs to be abandoned is the whole idea of Star Trek as a movie franchise. The only reason it worked for so many years is that the movies were the only way to see new onscreen material, but once the tv series took off, the movies became somewhat unnecessary.
Well yeah, but once again it's the only way to see new onscreen material. Just as it was back in the day.
It's a pretty easy argument to make that for the cost of that one movie, they could produce more than five seasons of a new series, with a lot less risk and better ability to respond to audience concerns. Plus, with a tv series, an established backstory isn't a limitation, it's a gold mine.
It's not a pretty easy argument to make. I think TV is more expensive than you think it is. Also, as of right now there aren't any audience concerns. And I think the last few seasons of Trek on TV proved that established backstory was was more lead weight than gold mine.
