Our family saw it today in IMAX 3D. It was AMAZING. I really loved it and thought it had something for everyone. I was also impressed that it was the first movie I've seen in a long time that every aspect of the movie was in 3D, not just little bits and pieces flying at you every now and then.
Since we actually live in Kansas, the tornado scene was a bit intense for my son, so he covered his eyes until that was over. We have the sirens go off and have had to take cover more than once in his life, so to him that was just a bit TOO realistic.
I liked the cast, loved the costuming. (Hello halloween costume merchandising!)
