I liked Kihmari's smooth sounding voice.

Tidus sounds whiny. I think even "I want everything" wouldve been a good line if it had been done in a more sensible voice.
But worst of all are those two girls at the begining who want Tidus's autograph. EAST BLOCK IN THE FRONT ROW pierces my ears every time.

I didnt have any strong like or hate for any voices but I really like the voice that sings the ending credits version of 1000 words in english
