Do you prefer the original or alternative ending?
I'm not sure which ending is the alternative and which one is the original. But I prefer the ending when Sara escapes the caves, pulls over to the side of the road to cry, see's Juno's spirit sitting in the passenger seat, and then screams her lungs out. Even though that ending didn't entirely make a whole lot of sense, I still liked it. It's the ending I prefer.
I hate the idea of Sara still being trapped inside the cave. I like the notion of her actually escaping and surviving.
