So Confused...someone help lol... [[spoilers]]

These are my questions:


What exactly were the pig faced things in the woods?

Why did they want to kill everyone?

Why were the people in the regular town so mysterious and touchy about it? (like the lady in the church)

Why was everyone in the tent at the end deformed in some way?

What was going on with the chick at the end...had she seen the light...what was it that the preacher guy said that made her so happy?



I watched the movie from start to finish...but maybe they didn't explain it clera enough? I am so confused lol...
