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.
It Was His Sled: The killer is probably known to most people who are familiar with the series. Though to those unfamiliar with the series, they still might be surprised to see Jason's lack of appearance.
Narm Charm: Mrs. Voorhees alternating her voice between her own and "Jason's".
One-Scene Wonder: Crazy Ralph appears twice in the film, and steals the show both times.
