---Doctor Korby: Are you with me, Captain?

This movie didn't have an extended title; it was just Star Trek. But I have some ideas for an extended title:
"The Unreal McCoy"
"Bad Robot Poops On Star Trek"
"Let's Pervert Star Trek To Appease Teenagers"
"Abrams Pilots Star Trek Over The Shark"
I have been a Star Trek fan for 42 years. I have seen every Star Trek story made for the movie screen and TV screen (including the animated series). This was one of the worst Star Trek stories I ever saw.
It was not necessary to "reboot" Star Trek. It was not necessary to change the Enterprise. It was not necessary for Spock and Uhura to have the hots for each other. It was not necessary to destroy Vulcan. It was not necessary to kill Amanda, although it was necessary to remove Winona Ryder from the movie.
There are good parts of the movie. Chris Pine and Zachary Quinto, who accepted the enormous challenges of playing Kirk and Spock, performed very well. Ben Cross, as Sarek, proved my belief that he would be a good Vulcan. The visual effects were very good, as I would expect from ILM.
However, the many changes in Star Trek history were unjustified. These changes can't be glossed over by saying, "It's obviously an alternate-universe story." That wasn't firmly established in the movie. (There is a difference between alternate-universe and alternate-timeline.) What I saw was J.J. Abrams, Robert Orci, and Alex Kurtzman rewriting Star Trek in a shameless attempt to attract young airheads who wouldn't care about Star Trek anyway.
The absurd design of the "new" Enterprise only reminded me of how beautiful the original NCC-1701 was. The "new" Bridge looked like a disco. The "new" Engineering areas looked like an oil refinery.
The other members of the new cast were mostly disappointing. Zoe Saldana is a lovely lady, but she couldn't carry Nichelle Nichols' boots. Karl Urban's performance almost was a parody of McCoy; he only reminded me of how much I miss DeForest Kelley. John Cho won't make me forget George Takei. Anton Yelchin made Chekov almost irritating. And Simon Pegg almost turned Scotty into the Court Jester (and why did they include that pint-size rockface? Is he the Jar Jar Binks of Star Trek?).
Kirk's rapid promotion also was absurd. No matter how good a young officer is, no one rises from Cadet to Captain that fast.
The soundtrack was forgettable. (I've already forgotten it.)
Obviously, nitpickers would go ape over this movie. The star dates - in the 2200s - would set this story in the first season of The Original Series (TOS), long after Kirk became Captain. Delta Vega was moved from the edge of the galaxy to next to Vulcan. The uniforms, like the "new" Enterprise, don't jibe with TOS or "The Cage." (They looked like cheap knockoffs I would find in a costume shop.) And how can the Kelvin carry 800 people?
If this was an alternate-universe story, then I hope we never return. I wouldn't mind seeing this young cast in another Star Trek movie, but I would want that movie to return us to this universe, where the Enterprise looks like the NCC-1701 of TOS, Vulcan still exists, and Amanda lives (and is not played by Winona Ryder). But I also believe this is too much to ask.
This "reboot" probably will be very popular with young movie fans. Thus, it might be the template for future Star Trek movies, in which we'll probably see more changes in Star Trek history. But no matter how popular this "rebooted" Star Trek becomes, it's no substitute for TOS or any other Star Trek series. If this is the only option for continuing Star Trek, then let the franchise die with some dignity.
