This is now soft opened, and I went out to Universal around 1:30 yesterday, they weren't doing any shows on any regular schedule, but I was by it when they started lining up for a ~2PM show (or a little after 2PM==edit it was 2:40pm we just lined up around 2). The screen and props are flat amazing, it's hard to tell at times when it is real or not. The show had a glitch toward the end and they had to stop it (there was a ton of management in the back watching) But it took a while to get through, the preshow room was half filled but the theater held more than the preshow room could (with distancing) so they walked some right from the indoor queue straight into the theater.
Show is legitimately good, lots of detail to take in and stunts were good, flow and lineup was pretty amazing. i'll have to go back to see if I can get through a whole show. (It died during the Dubai helicopter sequence) The weakest part was the plot itself, but the execution of the show was so well done I forgot about it. Visually stunning is the best way to put it. If you go to the park DO NOT MISS this.
The show was much better than what I expected originally. Precision accuracy in sets, action, and film, lots more live action than Terminator had, no 3D Glasses, but add in Broadway style moving sets and you got this show.
