I really liked the Lion, Witch and the Wardrobe, but not Prince Caspian that much..
To be honest, I prefer the books and the TV-series. The Lion, Witch and the Wardrobe used to be on TV on Christmas and/or Easter when I was little, so I have a closer bond and more nostalgic feeling towards the tv-series than the movies.
NO movie tops TLK for me, though. Not even Lord of the Rings or Bambi.
