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.

It doesn't help that they rejected some really, really good ones. Like this. Or this, by the legendary Shirley Bassey.
Complete Monster: General Medrano raped and killed Camille's family in front of her, and burnt down the house. He conspires with Dominic Greene of the organization Quantum, deliberately engineering a nationwide drought in Bolivia to get allow Quantum to get its hands on his nation's water supply and having the gall to frame the government for selling off its rainforests. Medrano is willing to plunge his nation into drought and famine, dooming multiple innocent people, just so he can have an excuse to seize power. When Greene informs Medrano how expendable he truly is to Quantum, Medrano buckles under pressure and acquiesces to Greene's demands before trying to rape his maid out of frustration. When Camille intervenes, Medrano tries to rape and murder her as well, mocking her about her mother and sister.
Contested Sequel: The movie is highly divisive. Either this is an okay Bond movie that's not as good as Casino Royale, or it's an egregious case of Sequelitisthat never happened. Skyfall was put in Development Hell due to studio reshuffling and licensing issues, making Quantum even more divisive over time and leading to a giant What Might Have Been: had the third Craig-era Bond film come out faster, would it have retained continuity and cashed in the plot coupons Bond picked up in Quantum? Well, we'll never know, as Skyfall more or less reset the modern Bond-era continuity againnote Though Goldfinger also had a one-shot villain, and the SPECTRE organization came back in Thunderball so who knows... — while he was a relatively new agent in Casino Royale and Quantum, Skyfall turned Bond into an elder statesmen almost ready for retirement. About the only thing the base can agree on is that Casino Royale and Skyfall each sit on one end of the Bond spectrum of seriousness vs. crazy-but-awesome... and then there's Quantum: a terrible Bond movie but solid film, or a solid film and solid Bond movie, or a complete Epic Fail. For what it's worth, many reviewers couldn't make up their minds either.
Post-Skyfall, the conflict regarding Quantum of Solace now seems to be about whether you prefer common Bond tropes averted and subverted (Quantum) or played far more straight (Skyfall) (though many of Skyfall's tropes are deconstructed, so keep that in mind). The debate seems to have shifted as to whether or not the next film should tie up the remaining plot threads from Quantum or stay in the Skyfall genre.
There is a small but growing camp that claim Quantum as the best of the Craig era, as it's the only one of the films where Bond seems to enjoy being Bond, and on that front is much more in line with the series roots than the poutiness and brooding that pervade Casino and Skyfall.
Continuity Lock-Out: You really shouldn't see this movie without seeing Casino Royale first. Skyfall requires you to see neither (or, alternatively, every film in the franchise), reversing the situation.
Critical Dissonance: The film did very well at the box office (it is the third-highest-grossing Bond film to date, without adjusting for inflation, earning $586 million worldwide), but it remains Daniel Craig's most divisive Bond film as far as critics are concerned.
Darkness-Induced Audience Apathy: This film took a lot of heat for being a Bond film that apparently really didn't want to be a Bond film. As such, it was really hard to care about anything happening in it, as nobody in the film came across as likable — the quintessential Bond elements were gone and the most common complaint was that the film wasn't a fun, escapist fantasy. Of course, given how Casino Royale ended, was there anywhere else to logically go? It's still a touchy subject in the fandom.
Agent Strawberry Fields, who managed to outshine leading lady Camille.
Fridge Brilliance: Craig was frequently criticized for his cold, emotionless performance, with one reviewer calling him a "Robo Bond." However, at the end of Casino Royale, which this film immediately follows, Bond's reaction to Vesper's death was...to completely shut down emotionally. Bond begins the film in the midst of a Heroic BSOD, and doesn't pull out of it again until the last few minutes of the film.
On the note of fridge brilliance, plenty of criticism was raised about one a scene taking place during a performance of Puccini's opera Theater/Tosca. The story of Theater/Tosca? A beautiful and successful singer is given a choice; betray her political beliefs and sleep with the evil chief of police...or her lover will be executed. It's basically mirrors what happened to Vesper. Also, the major song that plays during that scene is called the Te Deum where the villain is plotting to execute Tosca's lover even if she gives in. Like our villains, it's in a public place (a Cathedral in the opera whereas Quantum is in an opera house). Now it makes sense.
It's the Same, Now It Sucks: A common accusation is that the film simply repeats some things that worked so well in the last one — as well as the tricks of the Bourne films — except none of it feels new and fresh, let alone Bond-like. Arguably, the film actually contains a high HSQ and plenty of great lines, but it's too close to a Bourne film (or any other gritty action movie) to be a proper Bond film.
Magnificent Bastard: Dominic Greene might be a thoroughly nasty piece of work but he's a master manipulator and has balls of steel! He even manages to taunt Bond while being dangled over a raging inferno.
Mr. White as well. He is perfectly calm when taken to MI6 headquarters, kills Le Chiffre and his henchmen, and has his brilliant moment during the Tosca scene.
Moral Event Horizon: From Camille's backstory, one suspects that Medrano has made crossing this into a career. He's already a murderer, a torturer, an arsonist, and a rapist by backstory, so after he tries to rape the hostess, there's really no way his Karmic Death can be too harsh.
The incredibly mundane scheme by Quantum ( Monopolizing Bolivia's water supply) and the fact that their plan is foiled every step of the way despite American support, makes them pretty laughable villains, especially since they're a stand-in for SPECTRE.
The Problem with Licensed Games: Averted, with a solid, if not particularly inspired, FPS (even if it's more of a Casino Royale adaptation - only five of its twenty levels are from Quantum of Solace). The PS2 version is a TPS, and the DS is hard to describe. Incidentally, the Next-Gen and PC versions were done by Treyarch.
Tough Act to Follow: This isn't a badly done action movie, by any means, and it's definitely superior to a good number of previous Bond films, but it's definitely a step down from Casino Royale—which was one of the most acclaimed action movies of 2006, and is now often cited as one of the top 10 movies in the James Bond franchise. While it got generally favorable reviews from critics (it currently holds a score of 64% on Rotten Tomatoes), many fans trashed it after comparing it to Casino Royale.
On a similar note, many fans felt Skyfall was a massive, convoluted, narmy, self-important step down after the comparatively tight, focused, and serious Quantum.
