This movie is the perfect example of what you get when you put $100 million and the best crew in the world together and make a film: you get a technically excellent film, which any dolt can make with that combination (Scorsese, hello).
You don't get a story though, and from the try-hard actors slogging through their lines to the typical Hollywood tear-jerk cliches, this movie just has nothing interesting in it at all. Except the visuals, which are nice. Two stars for the pretty, and for Georges Melies. At about an hour, this would have been watchable, although stilted. Who thought that Sacha Baron Cohen could be off? All of the little jokes of this movie are flat, odd, and don't hit.
I agree with the person who said they would buy it on CD: That's the perfect place for it, a place where you can't see it at all.
If you get it for a buck at redbox, go ahead, as long as it's your sick day and you want to take a nap during something playing on the DVD player.
