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: Nine Inch Nails
Awesome Music: If you can get past the melodrama, quite a bit. Most fans admit that lyrics can enter the state of narm fairly frequently, (the chorus of "Where Is Everybody?", especially) but state that the music itself more than makes up for it.
"I pop the video in, and wow... Tears welling, silence, goose-bumps... Wow. [I felt like] I just lost my girlfriend, because that song isn't mine anymore..."
Broken Base: Reactions to Trent Reznor's film score work range from outright hate (much of the film score community) to hyperbolic praise (pretty much everybody else).
Another big contention amongst fans are whether any of the albums Post-With Teeth are as good as the ones that came before. A lot of the contention comes from the fact that the lyrical content and especially Trent's vocal style are vastly different than The Downward Spiral and The Fragile.
Ear Worm: Seriously, just try to get the drum patterns from each NIN song out of your head.
Ensemble Dark Horse: Live guitarist Robin Finck has always been the most popular member of the live band, and his return for both The Slip and Hesitation Marks was met with happiness from the fans.
Also, the demos of unfinished/rejected Hesitation Marks tracks from the deluxe version interview. Especially the first and second one.
Epic Riff: "Wish," "March of the Pigs," "Starfuckers Inc.," "My Violent Heart," "The Warning".
And not just on the guitar. The bass riff shared in the songs "Into the Void" and "La Mer" are arguably some of the most memorable from the rhythm section.
Fan Dumb/Hate Dumb: See Yoko Oh No below; Believing Trent's sideproject How To Destroy Angels to be the only thing keeping him from making more NIN music, a significant portion of the fanbase has taken to degrading and viciously insulting his wife and HTDA vocalist Mariqueen Maandig Reznor. A mild example.
The "Closer" video was purposefully filled with plenty of references to this trope.
Mark Romanek, the director: "I like how the front of [the microphone] looks like a little nipple."
Fridge Brilliance: "Mr. Self Destruct" and "Big Man with a Gun" both have the same tempo (100 BPM) and similar melodies. It could be chalked up to coincidence if not for the fact that "Big Man With a Gun" is the moment where the protagonist becomes fully corrupted and seemingly irredeemable- the very thing foreshadowed in "Mr. Self Destruct." Also, "Mr. Self Destruct" and "Big Man With a Gun" begin and end the first 'section' of the album (tracks 1-9, according to Trent).
It's Popular, Now It Sucks: Around the Broken era, NIN were gaining more popularity and some original fans decided they were getting too "mainstream". Trent himself didn't quite understand this trope.
Misaimed Fandom: Truly epic amounts of this surrounding The Downward Spiral as a whole. It's basically Trent exploring his nastiest impulses (hedonism, violence, Rage Against the Heavens, etc.) for 14 songs and exploring how things would end if he actually gave in to them (hint: not well).
"Where Is Everybody?"'s chorus deserves an award. It's essentially a List Song of words ending with -ing and Trent tries his hardest to stress every single syllable during the song's slow beat. "TRY-AH-YING AND LY-AH-YING, DEFY-HUH-YING, DENY-UH-YING..."
Vindicated by History: Fan response to The Fragile was rather lukewarm despite strong reviews, most likely because it wasn't as heavy as The Downward Spiral and didn't have a song with a chorus as memetically popular as Closer. However, a few years later fans have started to judge it on its own merits and it's now considered to be Reznor's Magnum Opus.
With Teeth also appears to be gaining more and more popularity nowadays. When it came out, it was considered one of his worst to date. Some fans, however, think it's a good album to introduce others to - Because, let's face it, most of Trent's discography is a bit too far on the 'weird' end of the scale for people to get into easily despite his success - and recently, it appears to be earning more credibility and more people are considering one of their favorites now than there were back then.
What an Idiot: The protagonist of The Downward Spiral's premature celebration at the end of "Ruiner." "You didn't hurt me... nothing can hurt me... you didn't hurt me... nothing can stop-" *cue "The Becoming"*
Yoko Oh No: Trent getting married and having a kid pretty much blew up some fangirls (and boys, as seen here). Fans blame his wife for him ending NIN as a touring project (indefinitely, though) despite the fact that he's expressed interest in trying something new years before even meeting Mariqueen, and create off the wall theories like "they're both on drugs!" among other things. Just go on YouTube and check out one of the songs in their band How to Destroy Angels and read the comments. It gets pretty ridiculous.
