This hasn't aged too well. The effects are dated, the dialogue is cringeworthy (at times) and the acting from the four children is mostly wooden, with Peter and Susan being void of any sort of charisma.
However, the story is still a classic of the fantasy genre and the score is magnificent. It's a solid children's fantasy flick.
I'd be fascinated to see another filmmaker have a go at adapting the Narnia novels as they had the chance of being up there with the Lord of the Rings of the genre.
Also, James McAvoy is creepy af in this omg he's come so far
