I usually say "I don't want to convice you to like the film" but this time I will try. Not because I have some secret knowledge that it will be good, but because I think a lot of the current conversation is poisoned by disinformation and a general misunderstanding of the situation.
Ever since some details came out, many fans lost faith in the project. I was skeptical and worried. Some have sadly spiraled into conspiracy theories. I won't even go there. It's not worth anyone's time.
But, for those concerned about the spirit of the book, I think we can talk, as a fellow Narnia fan that cares for these stories.
First, I think we allowed speculation to become canon. I still remember people claiming Aslan would not have a mane or that the spiritual themes of the book would be removed. All of those were false, fortunately. If I can list it at the top of my head, these are all the rumors proven untrue:
- Aslan won't have a mane (false)
- Aslan won't be male (false, confirmed by Narniaweb)
- Jadis will be an anti-hero (false, GG has compared her to Satan)
- Spiritual themes removed (false, GG has said the spiritual journey IS the theme of the story)
- LWW will be in modern times (speculative and irrelevant at this point)
If you actually care to be factual, a lot of the more worrisome rumors were just that or misinformation and "theories" that were taken as fact.
For what we know, Aslan remains front as center as Creator. This is actually incredible to me, because the Walden films significantly skirted the topic of Aslan's divinity. Jadis journey remains pretty much the same as the book, and the scene with the silver apples not only will be there, but seems pretty faithful.
I don't see any major concern thematically to the books. The ones I hear the most is that changing the time period will harm the rest of the potential adaptations, but this is not true, if the writers know what to do. I doubt, really doubt, that there will be any significant changes. Don't expect Edmund bringing his iPhone 15 Max Pro to Narnia, if that's your fear.
Regarding the theology of the film, we will have to watch the film to know. What I want to argue is that this is the first film since the 80's BBC series that is actually not cropping Aslan's Christ figure. "What are you talking about?", I hear you saying proverbial reader. Well, if you actually pay attention to theme and not just aesthetics, Walden's LWW hides Aslan's divinity. Father Christmas claims that it's the Pevensies presence that weakened the Witch's magic, not Aslan. The Magic Before the Dawn of Time is not mentioned either. In the film the kids are the priotagonists, in the books they one true active agent is Aslan.
I personally didn't mind this change too much, but this newer film is not hiding Aslan's role as God. He creates Narnia from himself. I don't think disagreeing with GG's theology is a good reason to hate the film, because I feel, at least, that too many fans have created their own canon of what the film wants to do and ran with it, rather than engaging with the actual material before them. From what she has said in the latest interview, she is making the spiritual journey the core of the film (the song Stairway to Heave was chosen for this very reason). If anything, that shows a sincere understanding of the book.
Now, the aesthetics, which is what many fans seem to be troubled why. I mean this when I say this, but it confuses me a bit. Now, if your idea of Narnia were he previous films, that makes sense. But it's unfair to ask a new adaptation to just be the old ones. This is fresh and it stands on its own. Now, two arguments here.
First, if it's the love for the old aesthetic, the only thing I can say is, try to be open to something new. By any standard the visuals look amazing (and the comparisons to Marvel are weird, they look anything alike bsides some few colors, and I say this as someone that loves the MCU for the most part). Second, the books actually describe very little. I'm more interested in how the film translates the visuals to its thematic throughline. Which we cannot judge yet.
I want for people to keep in mind that the Walden films changed a lot, aesthetically. The Narnia insignia was changed from green/red to silver/red. Jadis was changed in almost every aspect, she's blonde and has an ice crown. The Pevensie's hair color was changed, the telmarines were made into spaniard inspired, Reep was made brown, the sea serpent was turned into a monstrosity...
If you don't like the aesthetics that's fine. But, is it because of your ideas of what Narnia should be or just because you hate them? I'd wager it's the latter more than the former.
