I think you are missing the point. This new reboot is Star Trek reimagined. They are not going to make every thing as it was. They are going to mix a little bit of old with a little bit of new. I think the movie gets bad reviews from "fans" because of ideas like this. The movie is NOT wrath of kahn. It is NOT ST TOS, it is not TNG. It is JJ's star trek.
Most fans don't seem to have problems with it. It seems more of the issues crop up among Trek purists, or as I like to call them, people who think Star Trek isn't what it was because what it was isn't what they think it is.
