* AlternateCharacterInterpretation: The film adds the possibility that Susan's [[spoiler: eventual denial of Narnia]] is due to the romance that could never happen with Caspian.
* BigLippedAlligatorMoment: Susan and Lucy partying with Bacchus while the boys rescue Caspian. It has no impact on the plot, the mythology crossover is never explained, and it's never mentioned again.
* BrokenBase: The Caspian and Susan romance. Some invoke TheyChangedItNowItSucks and StrangledByTheRedString. Others were happy Susan had something to actually do in the film (as she did very little in the book) and liked the foreshadowing to her eventual fate.
* CrowningMusicOfAwesome: ReginaSpektor 's "The Call" at the end of the movie.
* DieForOurShip: The Susan/Caspian shippers, despite the fact that there's absolutely no mention of it in the books, they never see each other again, and Caspian marries Ramandu's daughter at the end of Voyage of the Dawn Treader. Curse you Andrew Adamson for [[ExecutiveMeddling including that kiss]].
* EnsembleDarkHorse: The geek at the train station ([[FanNickname Warren]]) gained a fan club when some fans decided they didn't like the way Susan's and Caspian's [[PromotedToLoveInterest relationship was treated]] and that "[[FanNickname Phyllis]]" was a much better pairing.
* EvenBetterSequel: WebVideo/TheNostalgiaCritic called the film this, praising the CharacterDevelopment, AdaptationExpansion and DarkerAndEdgier tone. He compared it to a proto ''Series/GameOfThrones''.
* HarsherInHindsight: The use of "The Call" at the end of ''Prince Caspian'' will likely become this if a film adaptation of ''The Last Battle'' is made.
* HilariousInHindsight: On the one hand, you have Ben Barnes, whose portrayal of Prince Caspian drew upon Inigo Montoya; and on the other you have Eddie Izzard, who based his [[{{Flynning}} sword-fighting]] mouse Reepicheep on ErrolFlynn, who also famously inspired Cary Elwes' performance. So their first meeting is really a ''Film/ThePrincessBride'' reunion by way of {{Captain Ersatz}}es.
* LoveToHate: Sergio Castellitto's take on King Miraz, making him a very effective and ruthless villain - with the occasional PetTheDog moment to humanise him. Likewise he also gets some good DeadpanSnarker moments.
* OneSceneWonder: Tilda Swinton returns as Jadis for one scene, as an expansion of a point in the book where they consider resurrecting her.
* RescuedFromTheScrappyHeap: Those who don't [[TheyChangedItNowItSucks hate the changes]] feel the film did this for the ''Prince Caspian'' story.
* RetroactiveRecognition: [[Series/GameOfThrones Tyrion Lannister]] is slightly grumpier, but quite recognizable.
* SophomoreSlump: Sort of. This was the second book published - though the fourth chronologically - and it's commonly regarded as the weakest. The film is a mixed bag. Some felt it was a step down, others loved it.
* StrangledByTheRedString: The romance between Susan and Caspian is accused of this. There was none in the book and it was DoomedByCanon anyway. The whole thing is very chaste and never progresses beyond simple flirtation - culminating in a small kiss at the end. WordOfGod is that the romance was more detailed in the original script, but cut down to a more chaste thing because they wanted to avoid it taking over the movie.
* TheyChangedItNowItSucks: This film provoked this more than the first. Due to the book's iffy pacing[[note]]The Pevensies arrive in Narnia, meet Trumpkin and then he tells them everything that had happened up until then (including Miraz storming Aslan's How)[[/note]], a lot of things had to be changed. Things that were especially disliked were the castle raid and the romance between Susan and Caspian.
* TheyWastedAPerfectlyGoodPlot: It seems like the movie is building up to something interesting with Miraz's wife being shocked to learn of his evil actions, but then she's largely forgotten about.
* UnfortunateImplications: Subverted. The Telmarines are given a RaceLift to become AmbiguouslyBrown Mediterranean people - WordOfGod saying this is to reflect their pirate origins. However both General Glozelle and Queen Prunaprismia are given AdaptationalHeroism to avoid having all the villains be like this.
* WhatAnIdiot: The assault on the castle in ''Prince Caspian'' (which did ''not'' happen in the book) gave huge helpings of this to Peter. To be fair, everyone from Caspian to ''[[TheHeart Lucy]]'' calls him out on it. Caspian also deserves a share of this one because it was ''his'' fault in the first place that they lost the element of surprise; he went into the castle with his own agenda and despite the obvious results of him changing the plan in the middle of a StealthBasedMission he shows no responsibility or remorse for his actions. To maintain order among the Narnian army, Peter has no choice but to let it go and share the blame.
* WhatDoYouMeanItsForKids: ''Prince Caspian'' was allegedly a children's movie and rated as PG. But despite that, ''Prince Caspian'' is probably the highest-bodycount, generally-dark movie to be given a PG rating since ''Film/IndianaJonesAndTheTempleOfDoom'' spurred the creation of PG-13.
