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: A Nightmare on Elm Street 4: The Dream Master
Rick's funeral scene. Alice falls asleep at the funeral. Rick's casket comes open and he gets out and begins talking to Alice telling her that it was a joke and he did it to fool Freddy. Seeing as how Freddy absorbs the souls of the people he kills and his habit of turning into people the heroes know, you would think that it would be a ploy by Freddy to scare Alice or perhaps in mind games. Nope, Rick tells Alice that he has to go, climbs back in the casket and closes it. Nothing evil or scary happens, nothing ultimately comes from it and is never mentioned again.
Fridge Horror: Freddy needed Alice to pull in new victims. It would seem as if Freddy was holding either the Idiot Ball or the Villain Ball for most of the movie by the way he was antagonizing Alice and seemingly intending to kill her. Of course, there are a lot of things Freddy could do to Alice that wouldn't necessarily kill her, but could keep her in a constant dream state with all the victims he could ever want at his disposal. Say, maybe a nicked brain stem or a concussion which could leave Alice brain dead...
Holy Shit Quotient: The zoom out revealing Kincaid isn't just in a junkyard, he's on an entire planet covered in a labyrinth composed of scrapped cars.
Squick: Freddy disguising himself as a human-like nurse. A make up-free Robert Englund in drag is suprisingly more disgusting than any violent act Freddy could dish out.
They Wasted a Perfectly Good Plot: As analysed here, the premise of Freddy exploiting Kristen's power to delay his death further and bring him more victims had a lot of potential that wasn't lived up to.
