I feel so sorry for Laurie...
Poor Laurie; he seemed like such a nice boy when he proposed to Jo, and before. After that, he was a less likeable...but I could understand after being turned down by your true love. Are we supposed to feel this bad for him in the book? Because in this movie, I can't help but see him as genuinely in love with Jo, which is what makes me feel bad for her rejection.
Then I feel almost equally as bad for Amy. I can't help but find her statements "I do not wish to be loved for my family" and "I do not wish to be courted by someone who is still in love with my sister" to be true. By that time, Laurie just seems bitter and determined to find a way to be close to Jo. Now, I'm not saying this is a "Water for Chocolate" situation, where he literally marries Amy in an effort to be close to Jo, but how can Amy NOT feel a sense of "second best" after all that's happened? Wouldn't you always be a bit worried that he would still have a slightly higher feeling towards Jo in the future than a simple "sister/brother-in-law relationship"? And Amy always did have a crush on Laurie. The only reason I don't feel quite as sorry for Amy is because Amy was always a yearning for popularity and riches, and it's hard to imagine that she still doesn't have that yearning. (Although, she did give up [Fred Vaughn?], who could have also given her those things. Maybe that's supposed to be a sign that she's changed}
