Going by how badly written, badly acted and badly conceived most of the recent trek movies prior to XI are to go by, I wouldn't want anyone to replace JJ Abrams right now.
But that's not what this thread is about, is it?
I think rebooting a franchise with so much history behind it is a bad idea.
What they did with Doctor Who was a better approach. I didn't like a lot of the RTJ Doctor Who, but I liked the _approach_ of not jettisoning the history, but just making it more modern and slicker. The new Doctor Who has production values that shame the final seasons of classic Doctor Who, but at the same time, they weren't afraid to directly link to the past, like by bringing back Sarah Jane. That's what the movie-era did to TOS, and TNG did after that. It's time for a sort of next-next-generation of post-Nemesis that simply does away with all of the Berman/Braga-isms (the wallpaper music, endless technobabble, downplayed drama, etc...).
Nor is this, really - it's just revisiting the same gripes already aired elsewhere.
