If you want a "realistic" Trek then you'd better get rid of Spock (human/alien hybrid), warp drive, phasers, transporters and all the rest of the trappings. If you make it realistic it won't be Star Trek any longer. If that's what you want then we need something to take the place of Trek, to update it. What's the best story? Since Trek became a franchise the best story is the one that makes the most money. Period. You could make a movie that would win the Oscar, Hugo and Nebula awards but if it flopped at the box office then it's reboot time. That's all well and good but I don't recall anyone in the movie actually mentioning slingshot around the sun as a means of time travel. Orci can claim what does and doesn't work all he likes but until they come right out and say you can't time travel that way then, seeing as it's branched off a universe where you could do that then his opinion is just that, his opinion. He's also said in an interview that Delta Vega is the same planet in WNMHGB and ST09. Doesn't mean that it is. It just happens to have the same name. For the Trek fans, this film includes many little references. For example you have Kirk dropped off on the planet Delta Vega, which was seen in second Star Trek pilot. It is a cool reference, but didn’t you also fudge canon by ignoring that Delta Vega was way out next to the galactic barrier.
