A few corrections
I must say, the movie isn't all that bad. However, I take objection to your portrayal of Gouki and his powers.
1. Gouki is not evil. He only appears dark and power-hungry because he is using the Dark Hadou. The Dark Hadou is not itself evil, it is just merciless.
2. Gouki does not allow others to fight his battles for him. He has honour and pride. He only uses his own strength - no weapons, no allies, no stolen power. That's why he hates Vega so much - because Vega only uses power that he has stolen from others.
3. Gouki does not want Ryu to "join" him; he wants Ryu to teach -himself- to be powerful, and he does not believe that Ryu can become powerful without the aid of the Dark Hadou.
Good work, though!
