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.
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.
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).
A 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.
Friendly Fandoms: As of late, the NIN fanbase is crossing roads with the fanbase of Queens of the Stone Age, of all bands. Why? Trent Reznor has collaborated with QOTSA for their latest effort, ...Like Clockwork, and the two bands have toured extensively across Australasia.
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).
Hype Backlash: Hesitation Marks got this with audiophiles after Reznor released an audiophile master of the album, free for anyone who bought the main album off the NIN website. Then the waveforms were examined, with clipping still obvious on the audiophile version, and the dynamic range of both versions were measured: the main version comes in at DR5. The audiophile version: DR6. Excitement quickly changed to backlash for releasing something as "audiophile" when it was not.
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.
Magnum Opus: Usually considered to be either The Downward Spiral or The Fragile. (Allmusic, on the other hand, gave their highest rating to Pretty Hate Machine).
"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..."
And before that, "The Warning" and "The Mark Has Been Made" appeared in Need for Speed Undercover; "1,000,000" and "Discipline" (both from The Slip) appeared in Midnight Club: Los Angeles and "The Hand That Feeds" appeared in Midnight Club 3.
Surprisingly Similar Characters: Like Einstürzende Neubauten, Nine Inch Nails' early discography contained frequent Sensory Abuse, and subsequent works moved on to somewhat quieter forms. Both bands have easily recognizable logos and their live performances' nature matured from chaotic and destructive to relatively normal and safe. The musical and visual characteristics of Nine Inch Nails seem more varied and electronic than Neubauten's. Anyone formerly or currently in the band lineup shares clothing styles similar to those used by Einstürzende Neubauten, but Blixa Bargeld now resembles Trent Reznor with a The Fragile-era haircut and the clothing he used in photos taken during the Preformance 2007 tour.
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.
Yoko Oh No: Trent getting married and having kids pretty much blew up the 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.
