Honestly, I'm really just happy that Cap's expanded so well globally. As for the numbers DOM go, it didn't crater this week, it (looks to) stay number 1 after the weekend actuals come in *fingers crossed*, and it's continuing to build the audience for Captain America, the character. (I admit if it the percentage was any closer to 60% and at number 2, I would've stayed off the boards the rest of the weekend).
Why would anyone be disappointed in its performance?
