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.
Hilarious in Hindsight: On a second viewing, you may notice that the terrifying scene where Hector is running for his life only consists of him running from nothing because he's told to (as Hector 2 only reaches Hector 1 just before the Cat Scare with the window).
Nightmare Fuel: The fist encounter with the bandage man and the discovery of the lab are extremely creepy, as is the movie's theme music.
Possibly subverted when you discover everything was planned out beforehand, and you see it mostly works out due to stupidity, chance and luck.
