Just caught a sneak preview of the 3-D version of the film.
It was very enjoyable, it has a lot of great action. The plot is not anything complicated or deeply philosophical, but I wasn't disappointed by it, either. I'll try not to give away a lot of details about it, but take the kids, and go see it.
Don't worry about spending the extra dough for the 3-D version, there are a few scenes where it is breathtaking, but I don't think it will ruin the experience watching it the old-fashioned way.
When it comes out on DVD, I'll be purchasing a copy.
