Having finally found time to see it last night, herewith follows my two cents:
1. I must add my praise for the casting. The children looked and acted like real
children, and not "movie kids" if you take my meaning. And of course Tilda Swinton was both regal and frightening, while Liam Neeson was perfectly believable as the voice of Aslan.
2. Unlike some previous posters, I found the spfx to be "state-of-the-art"--perhaps my standards are lower

. The lion was certainly more convincing than the "pantomime lion" used in the BBC adaptation, and I found the beavers to be quite realistic (we have them here in New York State, so I'm in a position to know

). In fact, the only character who came off as a little "cartoonish" was the Professor.
3. Regardless of who may have contributed funds to the film, there was certainly nothing in it that could be construed as heavy-handed preaching or moralizing. Indeed, it could be appreciated purely on the level of an adventure story in a fantastic land (a device used by many science fiction and fantasy stories--cf. "Through The Looking Glass"

). As proof of how effectively this works, a little girl in back of me burst into tears during the Stone Table Sacrificial scene--and I doubt she was old enough to have read the book or understood any of the story's Christian symbolism.
4. Very realistic depiction of England during WWII, IMHO. I think that "newness" of things in Narnia (mentioned by a previous poster) was simply to contrast with the very drab living conditions in England at that time.
5 Very cute putting a surprise "extra" scene in the middle of the credits
On the whole, first class film-making
