More like a BO loonie. I,ve been tracking BO since 1997. You? I've learned that once the film opens there's usually a pattern, so predict a gross after a second weekend is only a matter of history data.
And, for your interest, I've not seen MU.
I'm one of the very few here that does not relate success to stupid comparisions. Marvel vs DC, Pixar vs Dreamworks, DM2 vs MU. I don't care what grosses the most. I care about the gross of a film on its own.
