What a wonderful video. I liked the ending too. Yeah, a happy ending would've been fine and predictable, but I commend Kirsten Lepore for not going that route. Whether she was going for some deep meaning or just picked an ending arbitrarily, it works just as well as a happy one, perhaps more so because it makes more bold statement: That sometimes, no matter how two people (beings?) try to make a relationship work, it just isn't enough. Sometimes people are two different, or separated by barriers too vast to make it work.
I wonder if Ms. Lepore is an animation major/aspiring animator, or just an amateur dabbler?
