Dreamgirls Confusion

Perhaps someone can settle my confusion. Jonny and I went to the Arclight Theater yesterday to see Apocalypto (which was only okay). At the Arclight, they are showing Dreamgirls from this past Friday until its gets officially released on Christmas. The tickets are $25 and most of the showings are already sold out.

What is going on here? Is it possible that Dreamgirls is really going to be that good? I've seen the trailer and I am not even inspired enough to pay the regular $11 ticket price.

Regardless, I can't think of a film that I would pay $25 to see (unless it came with a dvd and a foot massage) let alone one that stars Beyonce Knowles. People remember that she sang Bootylicious, right?
