Extremely good in quality! Good drawing and effects and animation! I like it!
It's like the same story about winning over the Red army, but viewed from other angle!
The sound of falling dragon balls is like from wooden material, I imagined it should be like glass ringing.
When making the final kamehameha Gokuu is opening his mouth saying something, but we hear something else. Maybe they wanted him to tell one thing and then decided it to be another, but were lazy to overdraw the scene?
Hair on Gokuu's head is casting a shadow so this shadow moves one time in accordance with the hair and the other time it is still though the hair is moving.
Overall it's a good anime.
