What the hell is wrong with people saying that a GF4 would be good? I have about a billion ligitimate reasons as to why it would ruin everything.....1. The film would be made 20, 30 years after the first 3 films and that in itself is stupid......2. Why ruin a perfectly good trilogy with a movie that might very well be really shit....3. Mario Puzo is dead, leaving us with a legacy that will carry on for generations to come and....4. Why don't you leave well enough alone??????
