Batman Begins was a fantastic movie, I've seen it like 4 times. Chritian Bale's performance was magical, he was the right man for the job. The superb music and soundtrack created by the great Hans Zimmer was immaculate. He is the one who created the sound track for Xbox Halo game and for the Gladiator film. He's simply the best.
