Blasphemous erasure of all Trek history. --SPOILERS--

Rating: 1/10 (12 May 2009)

On SNL last week I saw the two actors playing young Spock and Kirk declare that they tried very hard "to stay true to Star Trek canon." This is a gigantic lie.
This film completely rewrites 42 years of Trek history. Everything is different, and they used the cheapest of all plot devices (time travel) to do it. As with all time travel plots, the paradoxes and logical inconsistencies batter you about the head until you just give up thinking. TIME TRAVEL IS SCIENCE FICTION FOR MORONS.
I won't bother to list all the specifics - you can read them here in other reviews, and they are legion. Vulcan is destroyed. There are two Spocks, the younger of which is having an affair with Uhura. Spock's mother and Kirk's father (and billions of other current and future people) are now dead or will never exist. The Federation (somehow) knows about Romulans and Cardassians already. It goes on and on.
Oh, and despite the Burger King commercials, there are no Klingons in the film. Klingons are mentioned a couple of times as a minor plot device.
The short version is this: if you liked Trek before this film, you will not like this film. This film brazenly "reboots" everything you ever knew. None of it ever happened.
I'm ashamed of Leonard Nimoy for selling out for this piece of garbage. Kudos to everyone else from the *REAL* Trek who stayed far away. In my opinion, this film will be rejected by fans as never having happened. This "alternate timeline" will never be true Trek to me, just like Greedo still doesn't shoot first. Retcon it all you want - I will ignore it.
