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: Blue Velvet
Alternate Character Interpretation: Frank is either a symbolic representation of evil, the Devil incarnate, or simply a psychopathic criminal. According to Dennis Hopper, the actor who played him, Frank is one of "The greatest male romantic leads of all time." Jeffrey's character is also open to interpretation. Sandy jokingly asks if he's "a detective or some kind of pervert" when he first suggests spying on Dorothy. However, after we see how Jeffrey reacts to the situations he finds himself in, we can start taking Sandy's question into serious consideration. Does Jeffrey genuinely want to do his share of good in the world, or is he becoming obsessed with the thrill this mystery gives him?
Complete Monster: Frank Booth, a sadistic sociopath with a penchant for random acts of rape and violence, is introduced by savagely beating and raping an abused nightclub singer and then taunting her about her mutilated husband (by him no less). It later turns out that Booth kidnapped the poor woman's husband and son (killing the husband in the process) only in order to make the woman his sadomasochistic sex slave, even cutting off her dead husband's ear and presenting it to her, just to torment her. When he figured out that Jeffrey Beaumont warned the police, he, in act of reprisal, beats Dorothy nearly to death, strips her naked, and leaves her in front of Beaumont's house. During the ending, we also discovered he has also brutally lobotomized one of his henchmen after having killed Dorothy's husband. Not to speak of raping the protagonist.
Foe Yay: Of highly disturbing and not very sexy variety.
Memetic Mutation: This film really helped the makers of Heineken!?Fuck That Shit!Pabst! Blue! Ribbon!! Then again, no one really wants to be like Frank so drinking Heineken might not be so bad. Additionally, Pabst Blue Ribbon was off the market for a long time due to poor sales. Perhaps this movie was the reason?
Compared to a lot of his other films, this one is actually really straightforward.
You could call this film a sort of middle ground between Lynch's more famous surreal style and the more straight forward structures of The Elephant Man and The Straight Story, since it has a plot that can be followed without too much difficulty, but plenty of creepy mind-boggling weirdness along the way.
The Woobie: Dorothy Vallens. Jeffrey in his weakest moments as well.
