The truth of the matter is, you lose a parent to murder when you're 10 years old, and in fact at the time of the murder you hate your lost parent, my mother in my case.
What I like about the third movie is you get to see a side of Carlisle you haven't seen before. You actually get to see what his vampire capabilities are because there's some great battle sequences. It's my favorite book. Carlisle is holding on to that humanity. He doesn't want to be a vampire.
So I'm not really quite sure what Landis' plans were to make another one. The American Werewolf in Paris was a completely separate story.
