Allow me to defend JJ Trek.

I don't think you need to turn your brain off to enjoy it. Sometimes small events do make big changes in history. While some people may have the same position in life, their life experiences may have brought them there in different ways. Also, consider how Kirk and Spock are literally told about Section 31 by Admiral Marcus, while in the prime universe, the DS9 crew don't even know they exist until Spoiler:

Bashir gets kidnapped by Sloan

, and even then it takes a while to get more information from it. The Abrams trek universe is no less intelligent than the prime one, but the path it will take the crew of the Enterprise will be far deadlier and riskier that it could have been without Nero's influence. The Abrams verse is no utopia, but its not as immoral as the Mirror Universe.

I'm repeating the same points over and over again, aren't I?

What I am saying is this, both the old and new Star Trek Universes are valid, both have good stories and interesting characters. Some times I like the old better than the new, like for Spock. Other times I prefer the new to the old, like Scotty, who is just funnier and more enjoyable. While old Trek is mostly set in stone, new Trek still has a while to go. Only time will tell if new Trek gets better or worse...

To be fair, I don't care about the increased sex and the lens flare in New Trek, although Into Darkness reduce these problems significantly.

Also, why doesn't the spoiler tag work properly?
