MY OWN COUNTER REVIEW
I disagree, I saw the movie and it left a lot of FUN questions to be resolved for sequels...yet it was all very well done, fast paced, and dazzling in its eye candy! It was quite understandable that the canon was to be re-imagined.
Perhaps “old Spock” can go back forward in time and fix his mistake there-bye correcting the timelines and fixing the Federation the way it should have remained, with Pike becoming disfunctional after being zapped with M rays and Kirk taking over after-ward as an older wiser captain...who knows! I won’t mention too many plot spoilers as others might still want to see it. I think the movie clears the way for all sorts of new adventures/fun possibilities with out the clutter of the previous canon while preserving the essence of the original characters and purpose of Star Fleet.
As for the Uhura issue, that might be a good thing, as it saves Kirk from having to worry about Spock having no one to Pom Far with every 7 years..(or having a planet to do it on...oops...spoiler alert!)
Didn't you see Back to the Future? Spock would be going forward to the future of the alternate timeline, which is pointless. He would need to go back prior to the Kelvin incident (the point where the timeline splits) and somehow stop Nero at that point.
