I think it's a good idea and they should have done it 5. The longest book being the shortest movie didn't work so well for me. Anyway, you're still getting two full length movies, so I don't see the problem paying for it twice. That's kinda like saying you won't pay for The Two Towers or Return of the King because you already paid once and you should get the whole story at once. More Harry Potter for me is only a good thing
