They are both good.
I really like how it continues to develop the characters.
Dick Hill is easy to listen to and does a good job using different voices for different characters.
Griffin definitely, Hill, sorry he sucks, his portrayal of the female characters is horrible, he makes them all seem weak and childish, Ernie Sage is not weak or childish.
I just like the story.
As above, he is great on the male characters, but on the female voices he is horrible, he kept pissing me off making strong female characters come across as weak.
Probably not, I doubt it would make a good movie.
