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.
Hype Backlash: Although by most standards it is a very good movie, people expecting to be given heart attacks on the spot might be disappointed if they've heard too much about it.
Love It or Hate It: In spite of good reviews and having its fans, some didn't like the movie upon its release. In fact, the first film was nominated for Worst Picture by the Golden Raspberry Awards and Heather Donahue even won for Worst Actress.
Paranoia Fuel: Try going to the woods after watching this movie and not feeling like something's watching you...
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), then you'll discover that the characters were doomed from the start.
Seinfeld Is Unfunny: In these days of dime-a-dozen "found footage" horror movies, it can be pretty hard to remember just how innovative the gimmick was in 1998.
