Sonic Vs Dr.Eggman Sonic saves the princes?
Nicely animated but I don't get it. What does Eggman want with Amy Rose? He's always been after the chaos emeralds.
Secondly, why Sonic? He's probably one of the less popular characters in the Sonic Universe. He's great for being used in comedy stuff but not in something like this.
I still give 9 because the bad stuff I noticed weren't related to the flash itself. More like author's preference, I guess.
