Hannah Montana 3D (U)

Before this week, I had no idea who Hannah Montana was. Now I gather she's an American tween singing sensation on her way to becoming a pop billionaire.

Which is nice for her. Hannah is apparently the alter ego of actress-singer Miley Cyrus, who between them rock out to an all-screaming, all-waving sea of pubescent worshippers. What with the dancers, the fireworks and the glittery costumes, it makes the recent U2-concert film look about as lively as a Rotary Club dinner.
