Don't spoil the ending!

*kh.... huuhhh* "LUKE.... I AMYOUR FATHER."

And just like that, all of Star Wars was ruined for me by the age of four.  I hadn't even seen any of the movies yet, but by 1989, this was such a commonly said phrase in American culture that any chance of me being surprised by the most important revelation of the trilogy was lost forever.  I still don't revere the movies nearly as much as those of you in your thirties and beyond, and I think this is one of the main reasons.  I don't like knowing what's going to happen before it does.  Suspense is cool stuff.
