I wanted to hate this series.
Not sure why, but I really wanted to not like this series from the beginning. Maybe it's my own problems of completing a series or even a pilot for that matter, or it could be that it would be another thing to have to wait and see the next episode for. Either way I just couldn't do it.
Backgrounds were all lined with appropriate perspectives and colored pretty well. The characters for the boys looked pretty similar just with a few color changes, but nothing too serious. Animation was pretty smooth and had some cool effects. Humor was great, a few jokes had been done before but I think you still used them effectively.
The only real problem I had was the voice acting and volume. Some people would mumble and talk really low in volume so Ii would turn up the volume and then everyone starts screaming and I quickly turn the volume down. It happened almost continuously, I would make sure next time to either lower the music volume or bring up the Voice.
