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 (2010)
Complete Monster: In life, Freddy Krueger was a child molester working as a gardener at a preschool. In death, he returned to kill all those who attended the preschool. He punctures one of his victims through the heart, then taunts him on the fact that his brain will keep going seven minutes after his heart stops beating. He keeps Nancy alive solely so she can remember him molesting her — before he tries to rape and kill her.
Hilarious in Hindsight: Johnny Depp tagged along to auditions for the original film with a friend. Wes Craven asked Depp to read as well, and Depp was cast other than the friend he was supporting. But fret not about the friend. 26 years later, Jackie Earle Haley would go on to play Freddy.
There's an interesting parallel between Marcus Yeon's final vidlog and this viral clip.
Older Than They Think: A lot of reviewers and people who watched the movie praised the introduction of micro-naps to the series as a clever invention. They were actually introduced in Freddy vs. Jason, in which Lori's father briefly morphs into Freddy in broad daylight when she's sleep-deprived.
Arguably present in the original, which would explain the more confusing moments of the film, such as the end where Nancy walks through the door of her mother's bedroom and ends up outside, while seemingly awake.
The Scrappy: Nancy Holbrook, often cited as one of the worst final girls of all time.
So Okay, It's Average: Critics approved of Jackie Earle Haley's performance as Freddy and the research put into the science of sleep, while also giving Katie Cassidy props for her performance as Kris; some reviewers even wished the film had made her the Final Girl rather than the decoy. However, they regarded the rest of the film as another failed attempt to recapture past glories.
Squick: Damn near everything to do with Freddy qualifies for this trope. Even before he was burned, his interactions with the children are unbelievably uncomfortable to watch, especially if you actually allow yourself to picture him hurting the kids.
