Quite short...
Personally I don't really like this kind of Flash movie. There are more of this type of movies on NG. You think "wow, great intro!" and then the movie suddenly ends.
This complete Flash, should have been the intro to this Flash! I expected that the actual Flash movie would start after this first sequence. But there was suddenly the "play" button again...
The animation etc... are all really good, that's not the problem! Just way too short and not enough actual content.
