** spoiler alert ** 
 I LOVED the first 80%. The last part was just not what I hoped for. Which isn't to say the writing is at all bad, I just don't really enjoy all this build up, and then bleh. Lou tells Will she loves him, and he is like "too bad." But he obviously loves her too, he just never says it. Even in his final letter, all he says is "Love, Will." I think there needed to be a true declaration of love. OR he really never loved her at that level, because why would he still think life wasn't worth it if he was in love?
