The American Film Institute (Star Wars: #13 greatest film ever, GFIII: Not in the top 100), the consensus of professional critics via Metacritic (GF3: 60, SW: 92), public polls, box office returns, depth of fan loyalty, impact on culture, and anyone who has taken note of movies that changed the way films are made, all disagree with you. Godfather III is a piece of shit. It just is. It's not a stretch to compare it to the Star Wars prequels -- for a movie that keeps the conventions, director, actors, and tone of the original Godfather masterpieces, it was as bad as could be done, and every bit the equivalent of the prequels in terms of disappointment and cringe-worthiness. This shit looks more like the beginning of a Batman movie than the end of a Godfather movie. I've seen better approximations of stereotypical "Italian overreacting" in comedy sketches. Setting aside how stupid it is to compare these apples and oranges, nobody agrees with you. And by the way -- you're the only one making that comparison. (Well I am now, but I'm just taking the bait here.) I had a point about the desire to hit up a long-resting franchise leading Coppola astray and I am correct about it.
I don't even fucking like Star Wars, jesus. I'm out.
Nobody was more disappointed by Godfather III than me. That movie was flawed from the start. Duvall's role should have never been cut which would have eliminated George Hamilton from the cast. Winona Ryder was originally cast as Mary but then pulled out due to illness and Francis then put Sofia Coppola in the role which was a huge mistake. Also the pressure from the studio to keep the movie at just over 2 hours nixed the plan to have flashback scenes to a young Sonny Corleone growing up and paralleling his life with that of Vincent. Would have been similar to the flashback structure of Godfather II. Had all of the above happened as they should have, it could have been a truly great film.
