I really didn't liked it
I am so sorry if you are one of the people who loved it, but really, I didn't liked at all.
1) The character of the boy... His acting... too bad.
2) The voice over of the boy... even worse.
3) The story... almost a cliche in Argentina. Every film is about the same.
I think we have better films here, but, it does not have the advertising Valentine had.
Maybe if spanish is not your mother language, the acting sounds better, but It seemed to me like a boy reading a book at the school, without any kind of acting.
And yes... the music is superb but... Agresti forgot to mention it in the credits, too bad.
