Narnia fan checking in! Loved the books as a kid, and need to re-read them in the original publication order (the numbering system most current editions use is, in a word, wrong. )
I loved the first movie, but the second two were fairly disappointing for me--I thought they made too many changes and lost a lot of the essence of the books (especially Prince Caspian, though to be fair, the book has a very unconventional structure and must be challenging to adapt.)
I kind of like the old BBC adaptions from the late 80s/early 90s. I haven't seen their LWW, and I thought their VDT was dull, but The Silver Chair really worked for me (in part because it features the illustrious Tom Baker as Puddleglum!)
I've also been dipping into Lewis's other books over the last few years...the firsts two Space Trilogy books are wonderful (didn't make it through the last one, which I hope to remedy eventually), and Till We Have Faces may be Lewis' greatest literary accomplishment.
