Just got back from an early(ish) screening on the first day of release here in the UK. I really enjoyed the film a lot. It's completely enchanting from start to finish and while it's not perfect, as an opening gambit for the franchise, it's pretty bloody good.
The look of the film is sublime, Narnia is as you imagined it when you read the books. The moment when Lucy first stumbles on the wardrobe is just spine tingling. And the final battle for Narnia is phenomenally done (if slightly botched by the ending of it). For every big exciting moment, there are many small and perfectly judged moments that further everyone's character. It really makes all the difference to a film like this.
Performance wise, the four Pevensey children range as a whole from hugely wooden to utterly natural over the course of the film. I assume that as the shoot went on, they became more at ease with their performances and as I doubt the film was shot in sequence, that would explain the unevenness from scene to scene. I haven't read any of the other Narnia books so I don't know if the Pevensey children are in all of them, but if they are and they retain these 4 actors, I imagine we'll see a Harry Potter style of improvement. James McAvoy is beyond cute as Mr Tumnus. He doesn't have much of a part, but he delivers a memorable performance, particularly his first scene with Lucy. And bear in mind when you watch it that in real life he has a very thick Scottish accent. I had paid no attention to the cast of people voicing the other characters, so it was a pleasant surprise when Ray Winstone, Dawn French, Rupert Everett and of course Liam Neeson all popped up. There is no denying that this film belongs to Tilda Swinton (as I had always hoped it would). She is glacial perfection as the Ice Queen, from her sweeping entrance to her sadly botched demise. Her hair and costumes are fabulous, but her performance is breathtaking. Anyone who can imbue the line "for sweeties" with as much resonance as she can deserves all the plaudits going.
Some moments are fudged and rushed, and some characters aren't given nearly enough breathing space (Jim Broadbent most prominently). There's some ropey FX work too. But those are my only real criticisms. The religious imagery is there if you want to look for it but it doesn't batter you about the head and shout "look! Jesus!" or anything. All in all, it's top quality entertainment.
Nothing precious, plain to see, don't make a fuss over me. Not loud, not soft, but somewhere inbetween. Say sorry, just let it be the word you mean.
