I'd seen a lot of the special effects and scared from the thing because it's so iconic and important in pop culture but i was totally blown away with the pacing, the soundtrack, Kurt Russell in general, Wilford without his mustache making gross faces when he's dissecting the creature. It's flawless. Same thing with nightmare. I'd seen the scene with the girl on the ceiling and Johnny depp getting absorbed by the bed, but the little synth stings when Freddy pops up, it was campy in the best way
