Some campy parts of the dialogue are legendary, but some things should simply be removed. Like parts of Drac's speech after defeat. I mean, he quotes the Bible..
It's a grueling death match between father and son, not the conclusion of a James Bond movie. It's cool Drac quotes it, seeing as he used to be a devoted man of God, but it doesn't fit the situation. Al's reaction is exactly what I thought when I heard it the first time.
