- Alternative Character Interpretation: In the 1992 movie, Curley's wife is far more sympathetic than in the book - specifically, the scene in which she arguably crosses the Moral Event Horizon by threatening to have Crooks lynched is omitted. The director wanted her depicted more as a "sad angel" rather than the vampish character she appeared to be in the novel.
She was told over and over that she must remain a virgin because that was the only way she could get a husband ... She only had that one thing to sell and she knew it. She is a nice, kind girl and not a floozy. No man has ever considered her as anything except a girl to try to make ... As to her actual sex life — she has had none except with Curley and there has probably been no consummation there since Curley would not consider her gratification and would probably be suspicious if she had any.
- Steinbeck once wrote to the original actress portraying Curley's wife in theater that she was sympathetic.
- Big-Lipped Alligator Moment: Lennie has a bizarre dream where he gets berated by his aunt Clara and a talking rabbit.
- "Holy Shit!" Quotient: Goes up exponentially in the final two chapters with Lennie accidentally killing Curley's wife and George killing Lennie.
- It Was His Sled: Lennie dies.
- Jerkass Woobie: Curley's wife. Loses most of the Jerk part in the movie.
- Memetic Mutation: Lennie's love of rabbits sprung from this novel, with Pop-Cultural Osmosis thanks to Bugs Bunny.
- The Scrappy: Nobody both in and out-of-universe likes Curley for a good reason.
- Squick: Curley's glove. It's not that it's full of Vaseline, it's that he's using it for his wife.
- Values Dissonance: The extremely sympathetic character Candy freely using the N word is pretty jarring now.
- "Weird Al" Effect: George and Lennie are far better known to modern audiences as characters regularly spoofed in Looney Tunes and Tex Avery cartoons ("Which way did he go, George? Which way did he go?") Tex Avery even made a cartoon based on the character Lennie called "Lonesome Lenny".
- The Woobie: George. The man constantly loses his job and seems like he actually is a pretty nice guy, but he has to endure a lot of pain since he travels with Lennie. He causes George to frequently lose his job and be on the run and George can't have a social life because he always has to take care of Lennie AND he forced himself to shoot Lennie. You gotta feel a LITTLE sorry for him because of that.
- Lennie, too. However goofy it may be, the scene in which he gets internal dialogue (with the aunt who raised him and with a rabbit) is utterly heartbreaking; he blames himself for everything that goes wrong in George's life (and he might even be right), and his biggest fear is being abandoned. And all he really wants to do is hold little animals.
- Curley's wife, to an extent. She's married to a badly-tempered man who is extremely possessive of her, and keeps her as a trophy wife. She's obviously lonely, but all the workers are too scared of her husband to speak with her. She later tries to chat up Lennie, which ends with her panicking when he won't stop stroking her hair and, when she starts to scream, him killing her by accident.
- Crooks. He's a lonely black man that isn't allowed to befriend the other workers because of his race. He receives no respect despite being one of the few, at least we know of, who once lived on his "own" land. He's now jaded due to racism and loneliness, explaining his attitude toward Lennie initially.
- Candy. The poor man lost his hand years ago, and he loses his beloved dogs, and eventually his dream...
- Broken Base: Between those who welcome the Nu Metal elements added and those who miss the Metalcore of the previous albums. This doesn't even begin to describe the reaction to Cold World.
- Subverted with Aaron's move to being the sole vocalist. The fans were very supportive of him and even highly praised his vocal ability.
- Face of the Band: Austin, then Aaron after Austin's departure.
- Harsher in Hindsight: "Pain" is a song entirely made of Austin's anger at the constant pain Marfan syndrome causes him. A few months after it was released Austin had to leave the band for good after doctors told him that due to his health issues, if he kept screaming he'd be causing himself permanent spine and nervous system damage.
- Screwed by the Network: The reason Jerry gave in an interview as to why he was only in the band for a year. Prior to joining the band he was under an exclusive contract with a different record label and they would not let him make any arrangements to terminate it.
- Signature Song: "Second and Serbing" for their earlier work, "Would You Still Be There" for their later material.
- Win Back the Crowd: Their post-Austin songs have been well-received for toning the Nu Metal down to a more manageable level a la Restoring Force and bringing back more prominent Metalcore elements, making their music recognizable as their own again as opposed to sounding completely different.
