Underrated
I think this is one the most well done movies I've seen for its kind. It's got everything, from the depths of despair to hope to laughter to joy. Bonnie Hunt did a heck of a job packing in all kinds of emotions in a realistic manner with likeable characters. I like how she gave honor to the first wife throughout the movie, it wasn't just a gimmick and quickly forgotten and realistically it is difficult in grieving and yet finding love again. This is not your ordinary romantic comedy.
By the way, I read something interesting for those who specifically receiving heart transplants vs any other organ and I wonder if this phenomenon is where Bonnie Hunt got her idea for this movie. It isn't too far fetched that Bob and Grace seemed to feel familiar with each other when they met.
