Educational
I was expecting to see a more violent death of a star, such as the Red Giant exploding and taking out the yellow one, but I suppose that wasn't really the point of the cartoon.
The point is, this is one of those rare educational Flash cartoons. Not that entertaining, but what they presented about stars was factual, so you might just learn something by watching this.
The animation was decent, but the cartoon was rough around the edges. Next time, be sure to put more effort into the voice-over; it was kind of sloppy. Also, proofread! If you're going to be educational, bee shure too hav corect spelig. It shows!
