There's nothing I have against it, but I only wish Lisa Ortiz would reprise her role as Amy. I have no problem with Roger Craig Smith as Sonic, but the only thing i would change is having Lisa Ortiz voice Amy.
I don`t like how harmless Eggman is in Sonic Boom. He`s less destructive and there`s not much action in it. Also, Tails doesn`t fight in the TV show. Like, at all. He dodges and all, but never attacks. I get he is the mechanic of the group, but he`s useful in combat too.
