I enjoyed it. The casting was well done with the exception of Sarek of Vulcan. The age of the "parents" of the youthful Enterprise crew made those cast changes much more jarring to a long time fan. Cleverly they used the time travel paradoxes to prevent long time fans from doing to much nitpicking. After all, time travel creates a new reality. Overall, it was well done. A bit overdone with the accents and the space battles, and I can understand that making a 1960's enterprise in the year 2009 creates some problems. But it was fun, and the younger Enterprise crew did well for themselves.
