ah, interesting--another friend felt that the changes from the book were for the worse. I have only distant memories of the book (A Swiftly Tilting Planet was my jam, however, and despite its faults contributed significantly to my studying medieval lit much later), and since Reason is almost old enough to understand/care, I'm trying not to revisit Wrinkle yet.... (Spoilers are fine or I wouldn't be trawling for friends' reactions, heh.)
