Sorry, but TOS was mid 20th Century Human behavior masquerading as the 23rd century. It was a commentary on then current events not a prediction/blueprint of the future.
ST09 is no "dumber" than TOS. It's in keeping with Gene's "vision". Just not his post TOS vision. TOS was an action adventure show. It had fights and explosions. It's characters had doubts and on occasion did the wrong thing. They disagreed with each other. They kidded each other.
Bingo. People keep trying to apply TNG standards to a movie based on TOS, which is kinda missing the point.
As I've written before, the universe of TOS was hardly the pristine, highly-evolved utopia some people want to remember it as. It was much more rough-and-tumble than that, with flawed, imperfect characters.
