I really enjoyed the film also but I am certainly willing to cut Herzog (and Cage for that matter) extra slack. If it was made by anyone else, I probably would have left it as mediocre...
That said, I thought Xzibit actually did an excellent job! That alone is pretty crazy, right?
And did anyone notice the random little person walk by Mr. Cage in that one scene? Am I being offensive by thinking that was perhaps a nod to "Even Dwarfs Started Small"?
