OOOOOOO!!!!! It's so good! But be warned, it's very brutal. Not bloody, just brutal.
At times there are so many high tension things going on, you'll be ready to jump out of your seat. My hubby said that it's so much better to watch at home because in the theater his muscles were taunt through the whole thing.
He let me go see it in IMAX on the second day. It was our wedding anniversary. He got tickets for the girls to see Space Chimps and told me to go in. Then he delivered Popcorn to my seat.
The guy next to me asked how I got it delivered and I told him. My hubby got applause! He is my hero. (he saw it two weeks later with my nephew)
That tension thing was purposely built in by the composer to take advantage of modern theater sound systems. As soon as I detected it I recalled the early attempts at that with the 1970's "Earthquake" and "Midway". If you have a large screen television of recent make you can purchase a speaker set that recreates that theater sound very accurately. Even a movie as old as "The Empire Strikes Back" becomes a whole new experience when you're able to hear it as it was intended.
And what a grand husband you have. Making the rest of us look like schmucks...(grumble)
