Actually, it was Jessica Alba as a blonde Sue Storm, but I get what you are saying. Suspension of belief is a major factor that makes any of these movies work.

Well, that, and a really good script. How many movies out there failed due to a bad story, even if it was a great concept to begin with (Green Lantern comes to mind)?

If I had a nickle for ever time a woman told me to get lost, I could buy Manhattan.
