Nice jorb, jhonka.
Firstly, I know the author of this movie very well, so my review is probably quite biased.
But on to the point: This is one of those things that people will either like a lot or hate its guts, which is also reflected in the other reviews here. And as you can see from the scores, I'm one of those who likes it.
The shortness doesn't matter to me, as it's the style that counts here. Feels like a weird Monty Python sketch. The length can also be explained by the fact that it's his first real attempt of Flash animation, sort of a test run (and therefore also deserves most of the low scores).
