The musical score is appropriately stirring and moody. The computer generated creatures are sophisticated to the point where the technology disappears and you begin to accept the performance, and not the special effect! This brings us to Aslan - if the talking lion didn't work, the movie would fold in on itself and go away. Aslan works,however, and works very well. Voiced by Liam Neeson, Alsan is both believable as a 'literal' lion and as Aslan, talking lion, King of Narnia. Aslan's face is expressive and noble, and Neeson's voice acting has strength and dignity.
This film succeeds on so many levels, it would be possible to discuss it in many different veins: the direction, the story's surface-level themes, the theological possibilities, the drama, the fantasy, the adventure.... Yes - it's an action film, a dramatic film, a fantasy, a somewhat-dark (yet hopeful) fairy-tale. It has humorous moments and frightening moments, like most truly great 'family' films always seem to have.
The bottom line is, this is a film that will leave you the better for having seen it. There's much to reflect on and much to simply enjoy - there's certainly enough to keep you thinking for a while, and that's always a good thing. Aslan, indeed, is on the move!
