Using Box Office reports, crowd reports, and Yahoo! user reviews, The World of KJ estimates that X-Men: The Last Stand has pulled in $39-42 million on it's opening Friday.

Michael Xia, a columnist at WoKJ, said the following regarding the Yahoo! reviews for Da Vinci, "My current projection for X-Men's Friday is $39-42m. The raw # of Yahoo reviews and the # of written reviews are all very impressive even with the ever-worse clogging."

WoKJ's users have been using Yahoo! reviews to track openers for years. While the system is not full proof, it generally produces a very accurate estimate. It should be noted that Yahoo! recent switch to a new home page has thrown some ratios off, because of this the ratio is harder to nail down than it had been in the past. This effect should go away over time as new ratios are generated.
