sounds like they’re trying to change the story more than they did the second one.
there are some tweaks and they did cut out some of the end details that would have slowed the movie at the end. Overall they hit the mark.
I understand why they felt they had to change the story. They had to keep the plot moving, and the way the book is laid out, there is nothing there to merge the events within it. If it was filmed that way, it would probably not make any sense to those of us who haven’t yet read the books.
Yet when these changes are approved by C.S. Lewis’ stepson, who is an avowed Christian himself, I felt confident that he would make the right decisions.
