Far too short.
This had so much potential, but it squandered most of it. The animation was good, though nothing to write home about, and the music fit, but the voices! C'mon man, fix these muffled voices and you'll have something good. Still, even with the quiet voices, this interested me, unfortunately it didn't last long enough. Two or three lines of dialog, a couple minutes of animation, and poof, it's gone. You have to make the next bit longer, or at least include a story. This is interesting, like I said, and I'd like to know more about these two guys, so do another. All you have to do is correct the nearly-silent speech and lengthen the plot portion of the movie. It'll rock, or so I hope.
