I had the impression that the USA guy was supposed to be a victim of the tower bombing who has now returned as an angel to bless and strengthen us survivors. It was banal, sentimental, funny at times, (especially the in-rushing flag-tide and the dunes-that-becomes-Rushmore). It would be more understandable if it were written and produced four years ago instead of now (and actually I don't know when it was made). But on the whole, its a lot gentler and less jingoistic than the really popular garbage from somebody like Toby Keith.
Numa Numa? I thought it was hilarious.
