It's bad. Terrible. Sora sounds real bad. Period. So far, his voice is as bad as Musashi's voice in Musashi Samurai Legend.
His voice should've sounded exactly like Haley's voice. Instead, Haley is trying to make him sound like he did KH1 and the ending result isn't sounding too good. It's going from deep to light to deep to light. Because of this, Sora doesn't sound like he's speaking naturally. He's now a character who doesn't know how he should sound. As a Sora fan, I'm very disappointed.
I'm now in full fledged support to have Jesse sing the Atlantica segments as Sora.
