lawman, it broke nothing. Show me what was broken by the Alternate Reality.
The entire argument boils down to Paramount, Abrams, Orci and Kurtzman trying to fix something that wasn't broken to begin with. Both with the way time travel stories are told within the Trek universe and the Trek franchise itself.
The reason City on the Edge of Forever, Star Trek IV and Star Trek: First Contact are all very popular is because the stakes. That if our characters don't fix things, then everything they know is lost. These stories are dramatically satisfying because of the stakes. The night I saw Star Trek 2009 I didn't care about Vulcan or Amanda because I knew these were just clones of the original designed to make me think something epic happened when nothing really had.
And let's all remember that it wasn't Star Trek that was broken. Those characters and stories are part of modern mythology for a reason. It was Modern Trek that was broken. The story telling had become stagnant and the general population had moved on.
So I do congratulate 'The Powers That Be' for coming in and fixing exactly nothing except turning Trek into 'lowest common denominator' fair.
Given that Enterprise failed, and Nemesis failed, Star Trek as a property was not "broken", but clearly needed an upgrade.
THAT is WHY this was done. To preserve past Canon (for us fans) while making changes necessary for a wider, more modern audience.
To say the fixed nothing is to ignore that a fix and a necessary upgrade are two separate things.
This is called a straw man.
The visual 'upgrades' were obvious.
But what exactly did they fix in way of narrative? Everyone goes on about how they've 'updated' Trek. But what I see was something that essentially just tried to take the popular elements of Trek, put them in a mixer and pour. I honestly did not see an idea one that seemed original to Trek in the entire movie.
This is just another Trek movie that desperately, desperately wanted to be The Wrath of Khan and yet seemed less intelligent than Nemesis.
