Even though I absolutely ADORE Pacino's acting, I have no problem in acknowledging he tends to overact from time to time, sometimes because that's the case with the character he has to play, sometimes just because he clearly enjoyes doing so. But I totally disagree that he overacted as Michael Corleone, not even in the less successful and worthy GF3. Pacino's Michael Corleone is absolute acting perfection, IMO. He brings chills of terror down your spine and tears of mercy in your eyes and is equally credible and admirable.
