I love Stubble Trouble, quite simply. It has that wonderfully bouncy character animation that 3d computer stuff cannot touch simply because of how 3d is done. The style of it is very cool, too. It has that rough hewn look, like it was scribbled on a cave wall (which is very appropriate). As for the story, its cute. Its not exactly Shakespeare, but neither was For the Birds, the short that that won the award. And rarely shorts are very complex. They have about 5 minutes to tell a story; if they manage to make you care about the character in that amount of time, they have done a very good job.
In short, if you can find this short, watch it.
