I went to see The Lion the Witch and the Wardrobe last night - drove all the way to Winchester for the nice independent screen there. It was packed. I was very impressed with the film - with a couple of caveats. Lucy (a crucial role) was just right. The designs were very much based on the Pauline Baines illustrations - excellent. But I was disappointed by the battle - much, much too big and long. Battles in Narnia generally involve a few hundred combatants and last a few (very violent) minutes. So as I feared the influence of Peter Jackson had a bad effect there. I also didn't like the silly frozen river scene. But many, many more good things than bad in the film.
And by the way, this column in the Guardian by Zoe Williams on the subject of the film's "dodgy" Christian subtext is well worth a read.
