Saw it this afternoon in IMAX 3-D. Had a great time, and tears welled up in my eyes a few times. Five minutes after the movie I was in my car sending friends a message about the experience that said, "Wow. Just Wow!"
When I got home tonight I sent a little more: "No spoilers needed as I won't give away any of the plot. But, I was really impressed with the work of the JJ Abrams crew/team in many ways. The movie is stellar entertainment for any sci-fi fan, but for an aging Trekkie it was just awesome. So much respect paid to the Star Trek of old and so much enthusiasm and promise for today's tech and tomorrow's tech, too, and a vision of a future that would make any Trekkie proud."
I really do need to see it again to write more specifically about what I liked the most. Yep, really do need to double- or triple-check my impressions...in IMAX 3-D.
