Beyonce talks to Oprah about her HBO documentary

As you may be aware — and given all the promotion, how could you not — Beyonce's life story documentary,  “Life is But a Dream,” bows Saturday night on HBO at 9. In this she talks about a lot of stuff, and she talks about some of this stuff to Oprah, who has an OWN special leading up to this Saturday at 8.

Anyway, long story shortened: Our most excellent music critic Glenn Gamboa has reviewed, and judged it, the doc, to be merely OK, and that it “plays like an infomercial.”

Sounds like fun! But he also says there are some interesting bits too. Here's his review.

Meanwhile, a couple of clips that a.) give you a flavor for this infomercial and b.) give you a sense of what Bey will tell O Saturday night. The first, by the way, is Oprah debriefing her before the red carpet premiere of her movie.
