I agree with you about your two movie choices. Second Hand Lions was fabulous; our nieces bought it for us last year.
And did you know there's a second Mrs. Miniver movie with all the same characters? It's wonderful. Not quite as good as the original of course, because it's after the war and the emotional level isn't quite as high, but a terrific story nonetheless.
No, I didn't know about the second movie. I only became aware of "Mrs. Minever" about 8 years ago; my sister was staying with me when I had my knee surgery and it happened to be on AMC and she insisted that we watch it.
