Ya know, I really wish people would get off this freaking dead horse. Sofia Coppolla did not do a real great acting job in GFIII. OK, fine, we get it. The movie is 15 years old now. Get over it.

You think Master Thespianess Winona Ryder, one of the great dramatic actresses of our age, would have done all that much better?? LMAO.

The part of Mary Corleone, as written, was simply not very interesting or complex a character.

Mary Corleone was supposed to be a spoiled, sheltered, rich brat, pampered by her mommy most of her life to keep her away from Gangster Daddy, who in turn overindulges her when he DOES get to see her, so needless to say Mary Corleone would probably have had a pretty oblivious "suburban princess" attitude, naive and not really very bright.

You ever hung around any 18-25 year-old "suburban princesses?" THEY ACT LIKE THAT. Like Valley Girls. "Like ohmigoddd, I am SOOO SUUUUURE!!" Shallow, vapid, selfish and not too bright. They believe in ponies and princes and Daddy buying them a new Corvette.

The biggest problem with the Mary Corleone character wasn't how Sofia Coppola played her -- it was a dull character to start out with.
