As a kid I loved this movie and I still like it but now that I'm older I understand it more and Sarah is alive so how could she be Elizabeth? And if the truth about Elizabeth had to be known for the spell to be broken killing Sarah wouldn't had made a difference. Also they couldn't leave witch didn't make sense cause of Sarah was Elizabeth wouldn't Sarah be dead and not have a family? If I misunderstood the storyline then sorry but that's the way I understood it.
