It stays very accuratly to the original dialogue of the book, which is always great to see.
There are a few slight changes to the storyline, eg. Aslan gives the children the gifts instead of Father Christmas, Maugrim has become Fenris Ulf, there is no robin to lead the children to the beaver and there is no mention of the housekeeper or why they are staying at the professors house. But I think these were done more to keep the length to a fixed time, they do not distract from the story at all.
The animation is fine although it will soon be 30 years old so it is not as good as some things around now.
We now have copies of this film with the English cast voices and the American cast voices and it really makes no difference which you have when you are watching the film. Although if you saw it many years ago it may matter more to you.
This is a very good introduction for children to this story as well as being highly enjoyable for adults.
The reason I have given it 5* is because of how true the dialogue stays to the book all the way through the film.
Extras listed are simply text information, there are no featurettes, clips, etc.
One word of warning, the principle actors have all been replaced with American dubs, with the exception of Aslan himself, so those looking to find the ITC (or PBS if you are from the States) broadcast version, you might be let down.
There is another version of this available on DVD with the original British cast, available only as Region 2 or 4 DVDs. This other version also contains commentary, although fairly limited according to those who have it. I'll take any suggestions as to where to find a Region 1 version.
Hope this helps anyone trying to confirm WHICH version of the animated feature this is.
