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.
Nightmare Fuel: Elijah falling down the stairs. Definitely one of the most disturbing depictions of breaking bones in movie history.
Seinfeld Is Unfunny: Somewhat averted. While the "Realistic Superman" trope has become very prevalent in pop culture, this film gets a lot of praise for kick-starting it and is commonly viewed as being a good film released at the wrong time.
Vindicated by History: When this film came out, superhero films were few and far between, and deconstructing something so obscure seemed bizarre. Today superheroes dominate the box office and Unbreakable would fit right in.
