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: Guns N' Roses
Big Lipped Alligator Moment: "My World" coming in at the end of Use Your Illusion II. Axl wrote that song all by himself while nurturing a love of Nine Inch Nails, and put it on without informing the other band members. Slash only found out about the song after buying a copy.
Broken Base: The fanbase is very split over the new GNR lineup and the Chinese Democracy album. On one side you've got the no Slash, so it sucks camp, the people who think Axl's jumped the shark, those who want a re-release of Appetite for Destruction, and those who simply don't like the new musicians and album. On the other, there are Axl fans, people who appreciate the talents of the "Hired Guns" and the new directions the music is taking, and people who just like Guns N' Roses regardless.
Ear Worm: Many songs, particularly those in the first album.
Ensemble Darkhorse: In a way, Izzy can be considered to be this. His guitar on Appetite and GN'R Lies was playing the same as Slash's rhythm guitar parts, only at lower volume, so it's hard to hear his playing at all, and yet he's one of the most popular members. During a concert in 2012 in the O2, London, Axl says "We wanna introduce you to a friend of ours. You might... you might know this guy. Ladies and Gentlemen: Mr. Izzy Stradlin." Cue the biggest encore GN'R has received since the Use Your Illusion Tour. For a guy who couldn't be heard on the albums he was credited on, he's pretty damn popular.
Epic Riff: "Sweet Child o' Mine". "Welcome to the Jungle" as well.
Jerkass Woobie: Axl Rose. His father was a control freak who raised him believing music and women were evil, he was sexually abused by his biological father and sister and physically abused by his stepfather and siblings, he has struggled with bipolar disorder, and his emotional immaturity is believed to be due to his abusive childhood. That's not even going into his messy relationships and his girlfriend miscarrying, ruining his chance to become a father. The guy's a prima donnaControl Freak, but damn, he has suffered in life.
Chinese Democracy is the prime example of what happens when a egotistical tyrant is given virtually limitless time and cash to record a follow-up album.
The twin Use Your Illusions are a lesser example of this, but it's clear that they had no leash.
Replacement Scrappy: Arguably drummer Matt Sorum. Axl certainly seems to feel this way; while he has described Slash, Izzy and Duff as "former members," he usually refers to Sorum as a "former employee." Ouch.
The Scrappy: To many fans, Axl Rose is an unstable, tyrannical egomaniac who is personally responsible for ruining one of the greatest rock groups of all time.
