I have never read the books by C.S. Lewis before, but this is still an excellent film that tells the story beautifully. It takes us on an emotional journey. Some parts were upsetting, some parts were hilarious, while some parts genuinely had me terrified... (I didn't know if the beavers would die or not.)
Some characters however were quite annoying, especially Susan, who played the 'realist'. I think it was intentional, but nevertheless, she got on my wick, as realists usually do, and for that, I have to knock off marks. Also my favourite character, Mr Tumnus was frozen throughout most of it, which was quite upsetting. That wasn't the filmmakers fault, as Mr Lewis probably wrote that in his book. But it is still rather sad, as I quite liked him, yet he only had a small part. All in all, I definitely recommend it, especially to those who are fans of fantasy. But it's definitely not my personal favourite.
