A better "ending" **SPOILER**
In the end credits scene where it shows 2 kids running around in the park and then it pans to Anna and William...where she is lying down pregnant....
Wouldn't it have been a BETTER ending to do that same pan...show Anna and William with kids already (or simply pregnant like the actual ending)...hanging out with the friend/disabled wife with KIDS OF THEIR OWN (assumed adopted)?
I never know why this film never gave the couple with the "disabled" wife an equally happy ending since she did bring up the fact she could never have kids
