- Anti-Climax Boss: The Endeavour, the flagship of Big Bad Beckett and possibly the ship with the biggest firepower in the franchise, being destroyed without firing a single shot.
- Author's Saving Throw :
- Fans who find Elizabeth to have become a Designated Hero once she chains Jack to the Pearl so the Kraken can kill him to ensure their safety would be glad to know that in this movie she shows great grief and is very conflicted about this and becomes The Atoner.
- Also fans who didn't like the way the relationship Jack/Elizabeth happened in the previous movie, despise it has been pretty obvious she will choose Will, the small relationship between them is mostly forgotten and even when Elizabeth thinks in getting closer to him he rejects her.
- Awesome Music: Hans Zimmer is always at his best, but special mention must be given to one specific moment. Gentlemen... hoist the colors.
- Big-Lipped Alligator Moment:
- The trippy peanut scene. Again though it was to showcase the madness of the Davy Jones Locker.
- The very beginning, with what is either a prison that executes inmates on an industrial scale or possibly the gates of hell. Of course, this was to illustrate how bad things have gotten for pirates now that Beckett has taken over.
- Complete Monster: Lord Cutler Beckett again. See that page for details.
- Darkness-Induced Audience Apathy: A variant sets in due to the overdose of Gambit Pileup and Chronic Backstabbing Disorder. Will, Elizabeth, Jack, Barbossa, Cutler Beckett, Davy Jones, Norrington, Sao Feng, and Tia Dalma/Calypso all have their own agendas, most of which change at least once over the course of the film and result in more Enemy Mine situations than you can shake a stick at. Some viewers had no choice but to resign from the story entirely.
- Designated Hero: Quite contrary to what one would expect this trope is subverted and pirates are rightfully treated as self-serving scoundrels who have been driven to a tight spot and fight for their survival not as freedom fighters. The fact that a lot of them hate and are ready to kill each other, that one of them is shot by a Pirate Lord for saying something that he didn't like and that Will remains sympathetic despite selling them all out to the EATC says a lot about how morally relative everything is and how only the main characters remain rootable even when choosing different sides on the War on Piracy.
- Designated Villain: Similarly this is subverted with Lord Beckett. He is meant to be unlikable not so much for wanting to put an end to piracy (Norrington desired the exact same thing and has always been considered one of the nobler characters) but because of the fact that he is willing to extort, cheat, manipulate and murder anyone in his way without a single qualm about their innocence in order to amass more power for himself.
- Ending Fatigue: Even those who like the third film tend to agree that the ending is overly dragged-out, meaning either the final battle or the tieing up of all the loose story threads.
- Hilarious in Hindsight: Chow Yun-fat plays a revered Asian veteran with a long goatee who sexually harasses the female protagonist. Two years later he was cast as Muten Roshi.
- Moral Event Horizon: The Big Bad Cutler Beckett crossed the MEH around the time that he had initiated mass-hangings for anyone who'd bought things from, sold things to, provided shelter for, or had pretty much anything whatsoever to do with pirates. This includes at least one ten-year-old boy hanged for piracy. This demeanour was foreshadowed and first displayed in the Dead Man's Chest when he had Elisabeth condemned to death for merely convincing Norrington to let Jack go, in order to use her as leverage to blackmail Turner into getting him the compass showing that he was ready to use and dispose of anyone who had anything that he wanted, pirate or not. And then he had Governor Swann killed both for knowing too much and for being of no further use.
- The HMS Endeavour being methodically wrecked without firing a single cannon, despite the fact that she has clearly more than enough firepower to engage both of her foes at once, all because her commander has gone Villainous BSoD and his lieutenant doesn't want to skip the chain of command even in front of imminent death. After so many admittedly impressive battles through the film, this one feels like an Obstructive Bureaucrat gag from a Terry Gilliam film and makes Beckett's demise incredible stupid.
- Speaking of Beckett, the sole fact that he goes completely blank after seeing coming both the Black Pearl and the Flying Dutchman can be hilarious for how jarring and convenient it is (as well as a bit of an Out-of-Character Moment). For a character who was serenity personified even with a literal gun pointed to his face and a magnificent schemer overall, he goes braindead in front of two ships which, supernatural or not, barely pose a challenge for his own (whether the Flying Dutchman could be destroyed is up to debate, but the film shows that she can receive battle damage and her crewmen are very killable), and that without counting the massive fleet he has behind his back. It almost looks like the writers realized they had written themselves into a corner and could not find a way for the main cast to defeat the EITC armada after the battle in the Maelstrom.
- Davy Jones standing in a large bucket of water also fits this. Jones is a fantastic villain, but even he can't pull that one off. It doesn't even make sense for the scene - how have they carried the bucket with Jones to the sand in the first place?
- One-Scene Wonder: Captain Teague, practically a no-brainer for this.
- They Wasted a Perfectly Good Character:
- Many felt this way that James Norrington was pushed to the background despite his character taking an interesting turn by becoming a crewmember of the Black Pearl in the last film.
- Captain Sao Feng. Despite prominent billing and space on the poster, he's barely in the film, doesn't do very much and ends up dying before the third act. Plus, he's played by Chow Yun-fat and yet he doesn't even get any cool action scenes.
- They Wasted a Perfectly Good Plot:
- The synopsis of the film explicitly paints James Norrington as Co-Dragons with Davy Jones, which sounds awesome, since he's the closest thing Jack has to a lawful counterpart and one of the few villains to both outfight and outsmart him. Unfortunately, the sheer length of the third film cut him down to three main scenes, none of which showcase him as dangerous, since Jones is The Brute and in many ways still The Heavy of the film.
- The AWE trailers' focus on the Brethren Court teased fans of the possibility of an epic fleet battle for the climax. Instead, we got a duel (if an admittedly awesome one) between the Black Pearl and the Flying Dutchman, with the 300-strong East India Company fleet retreating after Beckett's flagship is obliterated.
- The Kraken. The previous film established that the Flying Dutchman, while formidable, was not unbeatable, and a lot of the strength Jones boasted was due to having such a terrifying beast at his beck and call, rather than his ship and his crew; thus, whoever controlled the heart controlled the Kraken, and thereby the sea. Yet the Kraken is unceremoniously killed off between movies, without an explanation as to how, why, or what makes Jones still unstoppable without it.
