Awsome!
I thoroughly enjoyed this animation. I don't see why people need to get down on the song though. I mean yeah, you don't have to like it, but it's good for what it is. Personally I'm a fan of Against Me!, so that made this animation all the better.
The art could have been a little better, but once I took in the style and got used to it it was fine. Besides small little kinks like that, I really loved this. The animation, the music, the story, and how it all blended together. Very nicely done, a touching animation to be sure. :3
