I like THE GODFATHER PART 3. I mean it isn't up to par with the first two installments, but consider now that Coppola in spirit I believe didn't want to make this movie. I mean part of his deal with Paramount Pictures for the studio to finance and distribute Coppola's good movie that was TUCKER, that FFC would do GODFATHER 3.
As for Sofia Coppola...well shes a better filmmaker than actress for sure.
But its real interesting that after Coppola had no interest to do GODFATHER 3 after the sucess of GODFATHER PART 2 in 1974, Paramount tried to make a GODFATHER 3 for like 15 years...including at one point having Sylester Stallone(!) set to write and direct it. Yeech!
