Went with my wife, her brother-in-law, and her mother for Mother's Day. We all LOVED this movie. My mother-in-law (she watched TOS during its original run) said she had a tear in her eye at the end of the movie. I think I can say that the theater DID seem a bit dusty... We all wanted to stay and watch it again immediately - there's only been a few movies where that is happened to me.
On top of the movie being great, seeing it in IMAX was just over the top. If you get the chance to see it in IMAX, GO!
