Go see it. More than once. Then buy it when it comes out on video. No, Neil Gaiman is not paying me to say this.
I LOVED this movie. LOVED IT. I definitely am going to buy it, and when we get back from Paris, if it is still playing in theaters, I will go see it again.
It kept all the flavor of the book, all the heart and soul of the thing. That rarely happens when a favorite book leaps to the big screen. If you don't believe me, wait until you see the trailers for the Dark is Rising. They butchered the book, and they won't get a dime from me.
But Stardust is what a movie can be, if everyone respects where it came from.
