These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: The Blair Witch Project
Epileptic Trees: Fans have gone on for pages and pages debating what is attacking the main characters in the movie.
Rewatch Bonus: A lot if you check out the tie-in materials and backstory. If you know a certain aspect of the Rustin Parr story, ( that he marked the graves of the people he killed with piles of stones), than you'll discover that the characters were totally doomed from the start.
