Saving Mr. Banks: a film of two mismatched halves; one half is so joyless that it takes away (some of) the pleasure of the whole. What is worse, from a storytelling point of view, it’s a clunky resort. It does, however, portray well what can be behind creativity and how painful the process can be.  Emma Thompson, at first, seems to be doing a one-note curmudgeon (oh, but how well she plays that one note!), but her character rounds out and proves to be a great creation; Tom Hanks is earnest and charming and the rest of the cast, solid.
