First off, let me just say that i'll enjoy watching The Thing, a 600-pound creature made of orange rock, stop an oncoming 18-wheeler with his shoulder every bit as much as the next guy. But it's not the action scenes that get me excited about a movie like The Fantastic Four, which premieres on July 8. Whenever a new comic-book movie debuts, I get a kick out of seeing how the filmmakers finesse the science.
