I have seen all the Star Trek versions, and this is an excellent effort to re-invigorate the Star Trek universe. The casting and acting are very good (kudos to Karl Urban as a younger, more revealing McCoy), the story is engaging if initially covoluted, and requiring a suspension of logic, and the time-line shift to an alternate history allows for new approaches and more concepts for future movies. The Vulcan issue can be resolved by the discovery of "lost" colonies of Vulcans (as was done for the Romulans). Considering the dearth of creative entertainment available to the public today, we need all the "Star Treks" we can get. Live long and prosper, Star Trek!
