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.
Common Knowledge: Despite the fact that it would be impossible for anyone who has read the books to miss the fact that Narnia is one country out of many in the other world, many people think that Narnia is the other world itself.
Ensemble Darkhorse: Out of the four siblings and main characters, it seems Edmund has fared quite a lot, compared to the others. This is probably due to the character's Anti-Hero status that he still kept even after his Heel-Face Turn and especially due to the actor's natural dark, bad boy look that he easily manages to pull off without even trying.
Eustace Scrubb and Puddleglum are this too.
Reepicheep as well. Enhanced by the Prince Caspian movie.
Epileptic Trees: One such theory recently turned out to be true! A researcher found a thematic link between the seven books and the seven major planets (see Lewis' other best-known work, the Space Trilogy).
Esoteric Happy Ending: The Last Battle. The children will live in Narnia forever, which is what they always wanted (Narnia being Heaven), but it's still jarring to realize that, in our world, they're all dead.
Family-Unfriendly Aesop: The books contain the lesson that the real world is a harsh and violent place that sometimes takes a fair amount of violence to survive in. C. S. Lewis was even quoted once as saying that pretending otherwise would do a great disservice to children. Once again, an example of a very true and important Aesop, but one that many parents would rather their children didn't know.
Fair for Its Day: Lewis has taken a lot of flak for his Values Dissonance-laden statement in LWW that "battles are ugly when women fight." But other books do show that Susan and Lucy and Jill Pole are capable fighters and can hold their own in a battle. In other words, the statement is not that women should stay in the kitchen but that Men Are the Expendable Gender. Consider that the U.S. Military didn't allow women in combat zones until the 1990s, and not in direct combat at all until 2013.
Incest Yay Shipping: Well, since the four main protagonists are siblings...it was to be expected.
Mis-blamed: Some assume Susan was left out of Heaven due to pursuing "nylons, lipstick, and invitations", i.e. maturing, rather than the fact that she isn't dead yet. On the other hand, it should be noted that Jill's and Polly's (and by implication, Lewis's own) opinion was that Susan's notions of "maturity" were, in fact, immature and shallow, as Susan thought "growing up" meant going to parties and gossiping. Aslan makes it clear in Prince Caspian that growing up and actually maturing (even leaving Narnia behind for living on Earth) is a good thing. Word of God in a letter from Lewis to a worried reader was that Susan was still alive in England and 'might very well get back to Narnia in her own time and her own way'. Susan was meant to show how one could turn one's back on Grace. But once a King or Queen in Narnia, always a King or Queen. Given Lewis's personal history, it's probably safe to say that, to his mind, those who turn away from Aslan get the chance to turn back.
Yes, it's all very wonderful for Peter, Edmund, Lucy, etc. that they get to go to heaven with Aslan and live forever in paradise. But Susan (ignoring any discussions on why) has just had her entire family, including her parents, killed in a horrific accident. May also double as Fridge Horror.
A meta-example is that Lewis wrote The Magician's Nephew in order to do, in fiction, something he was tragically unable to do in real life: save his mother.
Caspian and Rilian's reunion, as the former lies on his deathbed.
Lewis has also been criticized for his treatment of Susan Pevensie in The Last Battle. Susan is criticized by her siblings and friends for being (in C.S Lewis's words) a "silly, conceited young woman," who has forgotten Narnia. This manifests itself in her love of "nylons and lipstick and invitations." Some critics have contended that this description paints an unflattering picture of his attitudes to women. Indeed, Lewis's treatment of Susan in particular and women in general, like his treatment of the Calormenes, remains a point of contention to this day.
People who think that Lewis is punishing Susan for discovering sex have clearly not read The Horse And His Boy. There, Susan is shown at the height of her beauty and sexuality and is treated as a good and gentle Queen. The point Lewis is making is that Susan has embraced shallow materialism at the cost of her friends, family and faith. Lucy mentions that it's impossible to talk to Susan these days unless it's about nylon and lipstick.
The Dwarves in The Last Battle, depending on who you ask, are extremely offensive portrayals of either Jews or atheists.
They also repeatedly refer to the Calormenes as "darkies."
Fan Dumb: The myriad number of Fan Fiction stories written after Prince Caspian was released that explain Susan's 'real' reason for later abandoning Narnia as lost love over Caspian, despite the two of them having no romantic interest in each other in the book, and very little in the movie either.
Even knowing he was going to die and later be resurrected, Aslan's death scene in The Lion, the Witch, and the Wardrobe. The sight of that great, proud cat, so cruelly bound, with his mane hacked off, knowing he is sacrificing himself for love... *cue hysterical sobbing* Simply how realistic and emotionally well done the death scene was. The parallel too.
The BBC version, however, is a completely different story. The buildup is sad, but the death sequence is ruined by The White Witch's acting (and the....shall we say, less than stellar animation).
And, precisely because you know what's coming, Peter and Susan's walk with Aslan near the end of Prince Caspian, and Peter's subsequent acknowledgement to the others that he would not be allowed to return to Narnia.
The final scene in Prince Caspian when the Pevensies leave. Throughout the movie you see the devastation the four of them have suffered at being ripped from Narnia and back into the normal world. And now they've finally come home again they have to leave. It's utterly heartbreaking and you realize that no matter what anyone says, or how old they grow, they're never going to recover from losing Narnia.
And when Lucy's glances back, Narnia's just...gone.
And the music doesn't help either. The lyrics are simultaneously perfect and horribly bitter.
"I'll come back...When you call me...No need to say goodbye...No need to say goodbye...
On a similar vein the end of the The Voyage of the Dawn Treader. Lucy and Edmund just look at each other and at the painting, suddenly realizing that's it. No more adventures, no more Aslan, no more magic: they're trapped in the normal world forever.
The end result of storming the castle in the Prince Caspian film is absolutely devastating - particularly the moment in which Peter looks back through the portcullis at the trapped Narnians, and at least one voice is clearly heard calling for him to save himself.
You see the Narnians at the gate, all screaming and trying hopelessly to get out, and you know that each and every one of them is dead. And the look of anguish on Peter's face as he realizes the same thing, and there's nothing he can do about it...
Props also to the brave Minotaur who held the gate open for as long as he could, only to be shot and crushed under its weight—a Heroic Sacrifice which saved many of the heroes, made even more poignant when one remembers that Minotaurs were "evil" in the first movie.
Lucy's goodbye to Aslan in The Voyage of the Dawn Treader. Made especially more poignant, when you remember that Lucy was the first of those siblings to find Narnia.
Eustace's goodbye to Reepicheep. Considering the development their relationship has had throughout the movie, that scene was heartwrenching.
Foe Yay: Between Edmund and the White Witch, especially in the The Voyage of the Dawn Treader film. He's haunted by visions of her on and off throughout the journey, taunting him about how he's trying to prove his worth. It gets especially explicit when she repeatedly offers to make him "her king", and that she can make him a man. Some of the things she says are borderline Mind Rape, stating that she'll always be alive in his mind despite the fact she's died arguably twice now (the second time by Edmund's own hand). Considered Squick by some for obvious reasons.
Mr. Tumnus. He lures a little girl into a small dark cave, lulls her to sleep with a flute, and when she wakes up, he's crying and saying he's been doing something bad.
The White Witch. Wrapping Edmund in her fur with her, being all close, asking Edmund to come to her castle, and to bring his siblings too. Jeez lady, and to only up the creepiness with Edmund, in the third movie, constantly whispering almost seductively, "Edmund, I can make you my King... and much more."
Though Edmund might've consented to a powerful, hot witch fawning over him. And this might have been partly why he joined her forces.
Unpopular Popular Character: Edmund Pevensie is the biggest example. He's the black sheep of the family in the first book, The Unfavorite and the villainous sibling from the main four, as he betrays his siblings to the big evil and torments and bullies Lucy. He easily becomes most fans' favorite character by the end of the second book and movie.
What an Idiot: Granted, Maugrim didn't think that Peter had it in him to kill, but that doesn't mean that jumping directly onto Peter's sword was a smart move.
