Except that Dan isn't working in terms of recriminations. He's thinking about how the films could have been improved. And one of his ideas, in particular, will blow you. (Away!)
2. Combine the First Two Films. Since the original Star Wars ("A New Hope") billed itself as "Episode IV," the prequels had to be three films. But they didn't have to be these three. In fact, I think most Star Wars fans expected the first of the three films to introduce Anakin, the second to cover the Clone Wars, and the third to bring Anakin over fully to the Dark Side.
Had Lucas stuck with that order, a huge number of the narrative problems and omissions in the prequel trilogy would have fallen away. First, Lucas himself has admitted that he had to pad out Phantom Menace to get to a full-length film. Making an Episode I that covered Phantom Menace's storyline in 45 minutes before jumping ahead 10 years to pick up the Attack of the Clones storyline would have immediately removed or drastically shortened a lot of the filler and the redundant plotlines - the Gungans (Jar Jar even would not have been so bad with five minutes of screen time), the storyline where Anakin accidentally destroys the Death Star-lite, the fun but overlong pod race, the repetitive fight scenes at Padme's palace. As a corollary, instead of being off in a star fighter Anakin should have been present for the final battle with Darth Maul. That would have presented several opportunities - have him witness the death of his first mentor, intensifying his emotional scars. Have him play some role, through a not-entirely-intentional use of the Dark Side of the Force (perhaps even a Force-choke on Darth Maul that isn't noticed by Obi-Wan) that saves Obi-Wan and lets him kill Darth Maul, thus (1) establishing Anakin's unusual precocity without the need for a midichlorian blood sample and (2) serving as a sort of original sin in his relationship with Obi-Wan. Personally, I would also have laid out near the beginning the death of Sifo Dyas, whose critical role in ordering the clone army is never explained onscreen.
