I am not going to put spoilers out or anything, but I have seen the show in Paris twice now and I am not over impressed. Not to say it isn't a success (people are queing like Fantasmic to get in), it just doesn't have the magic for me. I got bored waiting for the next bit and it really didn't hold my kids' attention.
I think if you are a James Bond fan or Fast and Furious fan, maybe you'll be ok, but for me I was waiting for it to end.
We'll have to wait for soft openings to see what everyone thinks. By all means experience it once but don't build this show up, then you won't be dissapointed.
Just my 2 cent worth.
