I think what makes this series so good (consider this a review for all of them to date) is that it's emotional, but without "trying to make a point." (Sorry this is going to sound cheesy-deep. Rest assured, I don't want it to.) When I watch them, I don't feel like I'm being pushed into believing or feeling the same thing as you were feeling when you animated them. Instead, I just see how you felt when you animated them, and feel only what comes to my own mind when I'm watching. I've seen very few other flashes that acomplish this as well as you have. Congratulations!
As a side note, I liked the third installment much better because of the longer length of it. Good work all around.
