I've only had one electrifying cinema experience and that was in 1996 for the opening night of Star Trek: First Contact. I had seen the previous Star Trek movies at the theater and liked most of them, but this was the only time I've ever been on opening night premier and the theater was packed with dedicated Star Trek fans who loved the movie! That made all the difference in the world, it was a very intense viewing as I was deeply into Star Trek and it was one of the best ST films..I remember the opening scene gave me chills as we see a close up shot of Picard as a Borg drone, the camera pulls back and we see more Borg in their cubicles, then the camera pulls back further and further until Picard is a reduced to a tiny spot and the interior of this immense Borg ship fills the entire screen. I was impressed!
I found First Contact quite so-so personally. I didn't like the way Picard's character was going (this continued in Star Trek: Insurrection) and found Patrick Stewart's acting very off, which in some cases could also have been a directorial issue. "That's what they came here to do: stop First Contact" is an especially peculiar line reading to me.
