The problem with the PT is it just doesn't work in order 1-6 for so many reasons. The focus on Anakin for the first three movies is gone by Episode IV. The special effects are SOOO different in both trilogies, and the whole tone of each trilogy doesn't jive as one continuous story.
Lucas could have changed the sequence with the Episode #'s this way:
Episode I - Star Wars
Episode II - The Empire Strikes Back
Episode III- Return of the Jedi
Episode IV - The Phantom Menace
Episode V - Attack of the Clones
Episode VI- Revenge of the Sith
Lucas could start TPM with Luke talking to his son some 20 years after ROTJ as an 'Obiwan' type role. It could flashback to him throughout the trilogy as he explains certain key plot points that Lucas is trying to convey, such as why Anakin chose to be Darth Vader. How fuckin cool would it have been for Mark Hammill to say, "And now this is the point where your grandfather was lost to the darkside!"
The different look with the new CG wouldn't be a problem to the older/newer viewer because it is essentially a backstory, not a linear story, so you can see how the Special Effects in the series progressed from 1977-2005. By telling as a backstory rather then a retelling of a linear story, Lucas wouldn't have been constricted of tying everyones fate up in ROTS with the last ten minutes.
The reason he had Padme die was so the story 1-6 would flow better, but as a backstory she could have taken Leia to Alderran and it could have ended there cause Luke is just telling what happened to her. Lucas wouldn't have needed to throw in the deathstar being shown and all that other bullshit cause he could have told just what needed to be told to flesh out the OT story, rather then do all these mirror tieins of both trilogies.
The PT should have fleshed out the OT and give it more depth the same way ESB/ROTJ fleshed out the story of Star Wars from 1977. It shouldn't have twisted the frickin story around so the OT is looked upon as different then the way we saw it before the PT!!!!! To me SW '77 is the first story that is told and the only story that is truly needed for any SW fan, cause it is the most basic, macro story of the 6 that really tells the overall story of all the characters involved in both trilogies, without getting too involved in any ONE character. The rest of the 5 movies are just more info about what we all wanted to know from the 1977 movie, and that is why Lucas should have told the PT that way. Instead we have this linear story that is so jarring, that you want to throw away the whole trilogy, and that is a real shame.
