This was one of those blatant heartstring movies. They take some characters and give them a horrible situation - in this case being unable to have children - and milk the sadness out of it as much as they can. At the risk of losing my man card - I usually love movies like this, but wasn't really hooked by any of the characters. No hook = no sympathy connection = movie is just kind of there.
I wouldn't really recommend people checking this out. Well, maybe it was just me and you'll connect with the characters and enjoy a sapfest. It just didn't work for me at all.
