It would be tough to topple the thrilling, booty-shaking pizzazz of her Beyonce Experience concert DVD of a few years ago. And while this DVD/CD package from the I Am ... Sasha Fierce world tour has a wider range of songs, they don't quite hit you with the same rump-rattling power of old. And just 51 seconds worth of Bootylicious? What up with that girl? We coulda handled it. Unlike Experience, which was just like being there, I Am ... is more like you had to be there.
