Just be Thankful George kept the "i've got a bad feeling about this" out of Raiders of the Lost Ark. I remember reading or seeing something in a documentary where he was Going to have Indiana Jones say this in the movie, sort of like the Wilhelm scream being in Both indiana jones and star wars series.
The prequels sucked because
A. The scripts were horrible
B. The directing Sucked
C. Over reliance on cgi to the detriment of the story
D. Hayden Christensen
They were largely not as collaborative pieces as star wars 77 and empire strikes back. It was on Return of the Jedi Lucas pretty much was writing the stories himself and all But Directed the film through Marquand.
Kasden did a quick tidying up on this script but had little to do with the stories ideas or story meetings. Remember he a director at the time and only did a quick re-write because he felt loyal to his past Relationship with George, and George gave him a stab a writing Raiders and Empire Strikes Back. Which to this very day are considered to be 2 of the finest scripts in genre fiction in hollywood history.
Okay Spielberg directed the Pre Viz for the lightsaber duel on Mustafar, But beyond that i don't know of George asking anybody to collaborate in his circle of friends outside his company of yes men and visual artists and effects technicians.
Even if Revenge of the Sith is by far and large critically and received by fans of the prequels as the best of the 3 the acting is horrible. The Lightsaber duel was pretty awesome minus the rediculous riding over the lava on droids part, and was really trying to be a redo of duel of the fates from menace. But Haydens " You underestimate my power" was beyond bad acting. And then of course you have the Emperor and Yoda acting like they are in a loony tunes cartoon. And then Vader walking like Frankenstein and goin N000000000000000000!!!. Nearly as bad as Shia swinging with monkeys like Tarzan in indiana jones 4, or the flying in a nuked fridge,lol. Indiana had a nice three mile ride through the air and just gets up and dust himself off.
The clones look like a cartoon and fake because they are all CGI. The voice over work by the Jango Fett actor "right away, sir" is also awful. I cannot believe Lucas saw fit to redub Boba Fett in Empire Strikes Back with this Clown.
Grievous Coughing too much like a bad villain out of inspector Gadget or something, the wheely thingy he rides is obviously only to sell toys.
They build up a character like Count Dooku to get killed at the very beginning of the film and his character was completely wasted in the prequels.
Midi Chlorian Subplot, the whills and the force ghost thing and qui gons fate in the force not explained.
Why did Obi Wan dissapear bodily into the force in star wars and then qui gon does not dissapear in Phantom Menace.
The prequels are such bad movies in a way they are entertaining in a morbid sort of way like watching a train wreck or a plan nine from outer space type of film.
The prequel trilogy is a bad remake of the oot without any of the charm or magic of the originals. In short a giant pile of shit. Still Lucas became a Billionaire because he has fans who drink the Lucas kool aide off of the prequels, and the bad 4th indiana jones made him further rich. When these films are so notoriously bad they should have been shunned like the star wars holiday special.
The only film to really bomb since Howard the Duck, Radioland Murders, More American Graffiti or willow was the 2008 Clone Wars movie. Everybody hated that shit film that was a proof of concept for a television series. Lets take a network animated pilot and put it on the big screen. Cause you know Pixar is making big bucks lets cash in on some of that success.
Maybe the Live action tv star wars series will be cancelled and moved from network to network like Young Indiana Jones Chronicles.
