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.
Anvilicious: Supporters, opponents and the author herself all agree that the book is as much a direct expression of the author's philosophy as it is a novel. They might feel, though, that Some Anvils Need to Be Dropped.
Canon Sue: Just about everyone agrees that John Galt fits.
Rand's style is a celebration of what she feels humanity can be at its greatest moments, and the "good" characters tend to embody that. As a result, just about all of them can be read as Sues. Your mileage certainly will vary.
Actually, had Rand been aware of the concept of a Mary Sue, she would probably have agreed that many of the characters are Sues. The thing is, they were meant to be archetypes, not realistic characters.
Critical Dissonance: Similar to the film as noted below, critics tend to loathe the novel, while readers tend to love it. Enjoyment of the book tends to correlate with one's political views, however.
At the beginning of the novel, Dagny's train is held up for hours by a red signal. She deduces that the signal must be faulty and that the train can safely proceed. This is because while certainly knowing the train schedule is useful (and in fact absolutely necessary for certain types of train control systems), the fact a train is not scheduled to be in the block does not mean one isn't there due to some unforeseen circumstance. Furthermore, while it would upset the point Rand was trying to make, knowing if another train is around shouldn't depend on the intellect of a senior official along for the ride. Train meets are supposed to be planned out ahead of time, and all crew members should know about them. What really makes everyone involved here Too Dumb to Live, including Dagny, the train crew, and Rand herself, is that a train occupying a signal block is not the only thing that can drop a signal to red. A broken rail, washed out bridge, or other critical defect can do so as well. The appropriate action in such a situation would be to contact the dispatcher or next station agent (by radio, or in the days before locomotives were so equipped, by walking to the nearest line-side phone box) and ask why the signal was dropped. Assuming no unexpected train was occupying the block, the dispatcher could then direct the train to proceed at a restricted speed allowing a full stop within half the line of sight in case a track defect was discovered.
But that's what Dagny has them do — proceed at a restricted speed until the next signal, then go on if it's green... Some Artistic License is involved, but everything Dagny is told indicates that this was a mistake, and that the signal is broken. It's not clear why she didn't send someone to a track phone, though, especially since she does do that in another train-related emergency in a later part of the book. It probably wouldn't be dramatic enough...
Rand also seems to have mistakenly believed that gun silencers render the gun completely noiseless, without even the soft "fwip!" of Hollywood Silencers. Maybe it is just another example of the super science that exists in the novel
Rails made of phlebotinum apparently cancel out the laws of motion.
Don't Shoot the Message: The reaction of a number of the book's fans to the film version. To some extent, the reaction of a number of Objectivists to the book as well.
I quite liked Dagny/Francisco to tell you the truth.
I actually was hoping for Dagny/Eddie.
The liberal Ho Yay may lead some readers to support Hank/Francisco.
Flame Bait: Like anything relating to politics. Mention you enjoy Ayn Rand on a liberal board and watch the feathers fly. Then, go to Free Republic and say its a dreadful brick, pour yourself some Black Label, sit back, and watch the world burn.
"Funny Aneurysm" Moment: In the book two of the first countries to elect socialist leaders are Guatemala and Chile and the US government completely supports this. Much fun is had at the expense of the Chilean ambassador and his wife, who are referred to as a pimp and a prostitute and given filthy habits. Over a decade after the book's publication, socialist Salvador Allende became president of Chile, and appointed the poet and Nobel laureate Pablo Neruda as an ambassador. Neruda died an agonizing death from cancer a few days after Allende's US-backed death and replacement by the fascist Augusto Pinochet. Thousands would be killed, many more would be brutally tortured and Rand's teachings would shape Pinochet's economic policy for years. And we haven't even mentioned the brutal Guatemalan civil war in which the US supported a military dictatorship that committed massacres against Guatemalans.
Harsher in Hindsight: The lights going out in New York City, after several real-life blackouts, including the aftermath of Hurricane Sandy.
Ho Yay: Hank Rearden and Francisco d'Anconia. "Greatest conquest" indeed. According to Dagny, Hank's "fallen for him!"
Hank Rearden is "the only man [Ken Danagger] ever loved."
It Was His Sled: Most people nowadays are aware of the strike and Galt's Gulch when they start reading the novel. Ironically, Rand originally planned to name the book "The Strike", but scrapped it when she thought it would give away too much of the plot.
Misaimed Fandom: The book is hugely and openly critical of torture and targeted killings, religion, and trusting feelings over evidence. It is very popular with the American far-right. AIG CEO Bob Benmosche is a fan, even though the villains of the book are CEOs who take government bailouts after causing an economic collapse through sheer ineptitude.
For Dagny, seeing that the looters are willing to torture John Galt is what finally makes her truly understand that they are beyond redemption.
Hank Rearden is considering whether Lilian actually wants him to have a miserable existence and suffer horribly, but he can't believe that she could be pure evil, because "to convict a human being of that practice was a verdict of irrevocable damnation... a verdict of total evil" and that "he would not believe it of anyone, so long as the possibility of a doubt remained."
What do you expect? Rand had an affair with a man twenty five years younger than her.
Values Resonance: Explains how a bestseller when it came out in 1957 has skyrocketed in sales since 2006 and after.
Vindicated by History: Although the novel has always been popular with readers, history not only gained it a phenomenal increase in popularity among readers but gradually increasing respect from political critics. This only applies of course to those who are inclined to support US-style libertarianism.
Jesus goes around recruiting disciples; Galt is making the creative people of the world go into hiding.
Jesus gives The Sermon on the Mount that's known to the world; Galt gives a speech on the radio that's heard the world over.
Jesus announced in advance at the Last Supper that he would be betrayed by one of his Disciples; Galt tells Dagny in advance while they're at Galt's Gulch that if she continues the way she is going she will betray him.
Jesus is delivered to his enemies and betrayed by Judas for 30 pieces of silver; Galt is delivered to his enemies and betrayed by Dagny for $500,000.
Satan offers Jesus the chance to be king of the world if he will accede to his demand to kneel and worship him; Mr. Thompson offers Galt the chance to be economic dictator of the country if he will accede to his demand to get the country off its knees economically.
Jesus refuses the offer and tells Satan that he has nothing to offer him; Galt refuses the offer and tells Mr. Thompson that he has nothing to offer him.
Jesus is shown the kingdoms of the world by Satan; Galt is shown to to the world by Mr. Thompson at the Wayne-Falkland hotel.
Jesus is nailed to a cross; Galt is hooked up to an electric generator.
His torturers take his clothes. (In both stories.)
Jesus is crucified; Galt is tortured with electroshock.
Jesus escapes from his tomb; Galt escapes from the State Science Institute.
Jesus returns to heaven; Galt returns to Galt's Gulch, the Striker's version of Heaven.
The Woobie: Steel tycoon Hank Rearden, believe it or not. Watching his mental strain when dealing with his unsupportive family and wife, as well as the government's policies which seem to be designed solely to choke him off from doing what he loves best, just makes you feel sorry for him.
Also Eddie Willers, Cherryl Brooks, and some named companies headed by generally decent people (notably the Atlantic Southern, which suffers one undeserved financial blow after another due to the looters' policies) all end up being this.
Tony. Just when he starts understanding what's really going on, he gets killed in a staged union riot.
For the films
Better on DVD: Many people, even if they disagree with a lot of Ayn Rand's political leanings have been quite patiently waiting for each film not because they like them, but because they aren't really interested in picking up that Doorstopper of a book their friends have ranted about.
Broken Aesop: The filmmakers resorting to Kickstarter to raise funds for the third film, when Objectivism is all about doing things on your own.
Critical Dissonance: 11% of critics liked the first film, while 74% of users on Rotten Tomatoes did. Whether critics approve of the film may be related to their level of agreement with its messages. The same is true about the users. Most of the people that saw it on their own account already supported its messages, while critics had to watch it regardless. The second film had a stupefying 0% Fresh on Rotten Tomatoes with 16 reviews and an average 2.6/10 score as of October 18, 2012. Fans rated 82% Fresh with around 3,300 votes and an average 4.1/5. As of November 16, 2012, the film had landed a single positive review with a total of 21 critic reviews. 78% of 8,297 had rated it Fresh, with an average 4/5.
It Was His Sled: A man is convincing industrialists and other producers to vanish by convincing them that society is exploiting them. This was a twist in the book that didn't become clear till at least 500 pages in - the man's existence was unknown for much of the earlier parts, and once it was, he was portrayed as a "destroyer" who simply sought to attack industry. The film, however assumes that people already know this is the story's premise and reveals it in the official synopsis and opening scene.
