Alright I know you've heard it before... but honestly. I mean I'm not even a fan of DBZ but I HAVE seen the series. And honestly Goku would win in like... the first few seconds. And that's not an over-exaggeration.
I really don't mind though as it's just a simple fun animation. But I couldn't get over the fact that the characters were really unrealistic. I mean there's no way Vegeta would die like that.
Anyway the quality of the movie was great however. The fight itself was amazing. The animation was smooth and crisp and the fight was played out nicely.
I just think you should have used different characters.
