Personally, I don't think that Superman will add much to the long term sales, although it will provide a short term increase which will help with the stock repurchasing (which adds on the bottom line later).
I think that cars will add short term and long term gains. It will help interest an new group in the hot wheels brand in the short term and long term.
And I think that the cars movie was great. And I saw it Sunday to a packed house. It may lose a little to Superman and the end of its run course, but it will continue to help in xmas when the dvd comes out.
And this is still a good company as it has good brands, some which are growing (American Girl), some which are struggling (Barbie). It still has good cash flow, and will not fall apart, but grow.
