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.

YMMV: The Lion The Witchandthe Wardrobe
Everyone Is Jesus in Purgatory: Word Of God says the book is hypothetical speculation on Christianity if Jesus existed in worlds that were quite different from ours. Of course, most people just thought it was a charming fairy tale.
First Installment Wins: The Lion, the Witch, and the Wardrobe is the best-known and most adapted book of the series.
Most of the casualties in the Walden movie's final battle are brought back to life either by Aslan's Breath of God or the fire flower potion. There was one real casualty, though: the griffon who is stabbed by Jadis' staff in mid-flight and shatters on the rocks below. The bad end? His body stays stone forever - in pieces - in an And I Must Scream frozen moment. The good end? He comes back out of stonestill in little pieces.
How horrible would it be to return to being a common child in 1940s England, with all the knowledge of twenty or so years of being an adult King or Queen in Narnia?
They all have to go through puberty TWICE now!
In the books, it was stated somewhere that memories of the real world become faint, dreamlike, when in Narnia long enough, and vice versa. This was apparently not noticed in the film adaptation of Caspian.
Hilarious in Hindsight: One Running Gag in the novel is that one should never shut oneself in a wardrobe, because if you do you'll be locked in. Edmund forgets this key piece of advice and does so anyway (although he is able to get out later). When the bloopers for The Movie came out, one of them was Skandar Keynes (who plays Edmund) shutting himself in the wardrobe, and consequently getting locked in.
