Oh dear, now I am in a quandary. I semi-deliberately haven't seen LWW, because I have such lovely images of Narnia and LWW in my head, I was afraid of what the movie might do to them. (I know, the movie doesn't change what's in the book, but sometimes movie images still end up crowding out, to a degree, the ones in your imagination. Or at least that sometimes happens to me, maybe I am just strange.)
In any case, after reading this thread I'm still unsure whether to see it. Had this problem with LOTR, too, though, but got over it and enjoyed the movies, despite their shortcomings. So I think I will eventually see it, as it doesn't sound like there is anything so horrible it will scar me for life or anything, but I am still a bit nervous.
