Base-Breaking Character: Kris, or more specifically, Katie Cassidy. Many critics and viewers gave Katie props for her performance as Kris, mainly for having more life than her costar Rooney Mara some even wished the film had made her the Final Girl rather than the decoy. That said, just as many are happy to point out that, while less flatlined, her acting is still fairly stilted and terrible, such as her infamous "There's this man... and he's BURNED!"
Complete Monster: Freddy Krueger is just as monstrous as in the original films. A sadisticpedophile, Freddy used to be a preschool gardener who would take the children to his underground cave, where he would rape them and take photos of them, his favorite being Nancy. When the parents of the kids find out and murder him, Freddy returns from the dead years later in order to kill the kids for snitching on him. In their dreams, Freddy gives the teens a head start so that he can enjoy their screaming and fear before he brutally murders them, all the while making snide comments at them. He then hangs the bodies up in his boiler room as trophies. Setting his sights on Nancy once again, Freddy saves her for last, so that, once her brain goes into a coma via sleep deprivation, he can keep her as his sex toy forever. Despite getting killed again, Freddy immediately returns, killing Nancy's mother.
Ensemble Darkhorse: While the characters are still underwritten, most people agree that Thomas Dekker and Kyle Gallner give strong enough performances to walk away looking fairly good.
There's an interesting parallel between Marcus Yeon's final vidlog and this viral clip.
The credits theme, "All I Have To Do Is Dream", was one of the covered songs on Freddy's Greatest Hits novelty album.
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. Doubles as Replacement Scrappy, since Nancy Thompson in the original movie was loved by fans for being proactive in standing up to Freddy, a trait which her successors carried into the sequels. New Nancy, in contrast, is a reactive character. Rooney Mara's later comments about the lack of enthusiasm she had for the role didn't help either.
So Okay, It's Average: Critics approved of Jackie Earle Haley's performance as Freddy and the research put into the science of sleep. 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.
