The core of Trek is science and exploration in the future. The characters are secondary. They can be anyone, in any race anywhere in the Trek universe as long as they are at least in the 23rd century. Kirk and Spock and this set of characters only have significance with the ORIGINAL fanbase, and these characters in NuTrek are not the original characters (not talking about the actors). Kirk, Spock and Uhura are only familiar names in NuTrek. They are not the characters we know. And what the hell is Spock? He does not have his logic, his Vulcan culture or any self control. He is ridiculous. How does NuKirk keep command of a starship? How is it he could just throw Scotty off the ship? How are these field commissions to First Officer and Captain being made? Its a mess.
Why would you think Abrams would not mess with Star Wars? Nothing in here shows otherwise:

I will watch it for sure! But Im not expecting excellence. Im expecting a lot of bones to be tossed to fans from earlier films, the appearance of familiar things, but they will be out of context and gratuitous. The script will be only secondary.
