I just saw it and personally, I was blown away by it. I can't say how well it translates to a recording on TV or Youtube, but in person it looks absolutely insane. The show is so much more than the sum of its parts. I don't think any one effect in this show is more than okay, but when its all moving in sync and the action is in full play, the show is probably the best show in Universal and overall attraction of this modern age of 3D attractions (TF, Simpsons, Fallon, Kong, Diagon.)
I've heard worry that the street fight will mess with the flow of the action, it is the very first thing you see in the show. There isn't any flow for it to interrupt.
The seats don't move but the audience perspective is basically used as "the camera". Set pieces will turn and grow vertical as the HD screen background does making for some amazingly dynamic moments. There are times where I found myself wondering how they did a thing and then stopping my train of thought because that would ruin the magic. None of the effects are very hard at all to figure out, but they fit together perfectly.
The preshow is a little messy. The green screen effects are pretty gross and there is an absolute ton of exposition and setup thrown at you needlessly. I can't defend that aspect. Once you get in the theatre however the show knows to not let the story get in the way at all, which is all it pretty much needed to do. Plot synopsis: Bourne is about to leak info, bad guy CIA goes after them, good guy CIA gives him intel to fight back, he fights back. Don't think about the plot too much and just enjoy the spectacle. Anyone expecting a huge LOTR-esque story needs to rein in their expectations for this or any stunt show. None of them are high art exactly, but they are definitely awesome to watch and have fun with.
Wait until you can see it live to make up your mind, I haven't seen a Jason Bourne movie in my life and was able to see T2 a decent amount when it was here and still think that this blows every other show at Universal out of the water completely. Would watch again.
