If there's ever an argument that leaning on Star Trek's past is guaranteed to work against it in the future, the TWOK-redux portions of Into Darkness pretty much define it.Into Darkness redid Wrath of Kahn (in my book that's blasphemy)
Star Trek should always be moving forward, and my thought since seeing STID has been that with the Khan story out of their system, Orci, his writers and our new fearless leader director can craft something amazing.
I watched STID last night and the feeling I got at the very end of the film was: Ok, now we have all the origin story, Khan, Starfleet is an army/no it's not stuff out of the way, let's get to exploring. I would love to see an entire nuTrek movie where they never went to Earth or even mentioned it.
Have you taken a look at the ongoing comic series? The next arc beginning in January is the beginning of the 5 year mission. Not really considered canon, I know, but the series has been pretty decent.
