Pretty.
Positive: That's really the best way to describe this flash. It's pretty; and kinda cute. Enjoyable music, well-designed graphics, and an immediately likable character make this an overall positive animation experience. I was especially impressed with the hand-motions of the robot on the guitar, which were more realistic than most animators bother with. Good show.
Negative: Not breathtakingly beautiful nor particularly memorable. I enjoyed watching it, but I feel no compulsion to show it to anyone else. Good, for certain, but not awesome.
