Thanks to the concept of Nightmare Fuel, Freddy's "fuel injection" line is now more appropriate than ever.
Decades before Freddy's appearance in Mortal Kombat 9: Amanda wins. Babality!
"Holy Shit!" Quotient: Alice dreams of her womb and her baby. She's happy at first, until she realizes Freddy is there too, and has been feeding the souls of his victims to make the baby evil like him.
Misaimed Fandom: At one point, Freddy forcefully fuses a character with his motorcycle. The process looks very painful, with pipes and wires piercing through his flesh, skin peeling off and pieces of machinery inserting themselves into his body all over. It is...gruesome...and if you look the scene up on Youtube and check the comments, you will find people talking about how badass the resulting being looks, and how it should get its own movie or comic book series.
Some Anvils Need to Be Dropped: Alice's right as a mother is explored upon in this film. The film doesn't try to pass moral judgement on abortion, nor is the process considered right or wrong. When Mark asks if Alice has thought about not having Jacob, Alice says no because she considers him a part of herself and Dan, not because she thinks the idea itself is wrong. The whole film is about Alice trying to keep her child from other people, such as Freddy, who is trying to warp Jacob into a tool he can use, and Dan's parents, who think they have a right to Jacob because he's their grandson and even refer to him as "It." In fact, Dan, despite dying early in the film, is given more consideration than Alice is, as Alice's own doctor actually called Dan's parents and told them she was hysterical. The film treats this course of action as wrong.
Special Effect Failure: For all the great looking practical effects in it, the few moments of stop motion used look just out of place, especially when Alice sees the food in her fridge rot away before Greta appears to her.
Squick: The film is so squicky that it's the only Elm Street movie to have an unrated version.
