This is my favorite of the trilogy.
The first part is nostalgic, so I hold it in high regard even though it's not a perfect movie. In terms of quality however, I liked this one the most. It has a dark tone which fits (unlike The Voyage Of The Treader where it actually became kind of ridiculous) and I enjoyed Ben Barnes as the prince.
It's the only part I gave an 8 to, since it held up the second time around too.
The Lion, The Witch And The Wardrobe is still always fun to watch, but holy crap, it sure is a cheesy movie.
