I'm fresh out of the theater from seeing Star Trek: The Menagerie. I was really excited to see the episode on the big screen. It was the re-mastered version and it looked amazing. The scenes that really stood out were the space scenes; the stars are now in 3D. The ship looks 100% better. The ship is totally CGI now (I think). There was one major scene that was re-done. It was an overhead Enterprise shot of the crew. It was phenomenal and worth the ticket price alone.
As far as the audience, there was only one guy in a partial uniform. I had on Star Trek earrings but you had to really be in my face and know the logo to tell. I didn't really see anyone in Star Trek t-shirts. To my surprise, I didn't see any of the usual Trekkies out either. The theater was packed and the audience was responsive. We even applauded at the end.
I went to the Houston showing at Studio 30.
