Every time I’ve tried to pick a favorite (and I’ve tried many, many times over the years) I can’t do it. I’ll say “Oh, Dawn Treader is definitely best!” then think to myself “… but Puddleglum is so cool, and the whole giant castle. And in Horse and His Boy the whole arabian thing really caught my attention as a kid. And of course Lion, Witch, Wardrobe started it all…”
So really I’ve decided to consider the entire series one big book (which it could be, none of them are very long) and say it’s one of my fav books ever.
I do wish someone would do a higher-quality movie/series out of it. I liked the most recent movies, but they were good, not great. I want something on the level of the Lord of the Rings movies.
