I was bored one day and decided to watch Sita Sings The Blues after reading a few good things about it and also it being free. I thought it was one of, if not the best, animated film I have seen in how it shows, through a versatile amount of forms such as watercolor, collage and others, the artistic power of animation. Also the story is interesting and the music is greatly synched to the story and animation. After watching it, I was so inspired that I tried to animate something myself and quickly saw that it was not as easy as it looked. Nina Paley did an admirably great job making this.
Now watch it.
