So the big scare (SPOILER)
So the ending leaves us with two possibilities. One, the group is left to die (all were buried alive though we only saw Brandy actually be buried in a plain wooden coffin. The others were in nicer more modern coffins but still coffins)or they all were released in time before they did. Thus the ultimate scare was truly thinking they were being murdered.
Or they were killed because they discovered the secret or upset too many haunted house owners by filming when they were told not to.
I imagine they were released, hooded again, walked to their camper, told to wait 10 minutes or so before taking to hoods off, and then told to never come back. Oh and all their film taken.
So then, if the latter, how did we see the movie??
