Re: Uhura replacing McCoy/Bones?
Worrying about the accretion of lore from hundreds of hours of films past is what made Trek progressively uninteresting to folks at large and brought the franchise to a dead halt. I'm quite happy they made it as they did, playing for a new audience rather than playing to the small audience of hardcore Trek fans who care about such minutia.
