There is little left to say about the singular Celine Dion that anyone who has ever been near a radio or has ever shopped anywhere doesn't know already. If you love her, then you probably know all about her recent past, in which she held court in Las Vegas for five years. You know that nearly all of those shows were sold out and that over that time, she performed for some 3 million people. And you probably know that her Friday stop at American Airlines Arena in Miami is part of her Taking Chances World Tour, which kicked off last year in support of her latest English-language greatest-hits album, My Love: Essential Collection. And if she's not your cup of highly emotive tea, well, if you steer clear of this show, you know that your heart will still go on.
