Yeah basically i always knew Return of the Jedi was 4 films squeezed into 1.
Lucas was burnt out and deserved some time off.
But not doing the Sequel Trilogy was a major copout.
He could have taken a couple years off or a few years in bewteen trilogies and still finished all 9 films.
It could have been accomplished with the 1980's technology and did not need to ruin the saga.
There would be No Jar JAr, no Young 8 year old anakin, no qui gon none of that was in the outline for the prequels.
I have never had a problem With Vader being the father and Leia the sister as it makes the saga more like the Mythologies lucas read up on in college. The greek, roman, and norse myths.
But the prequels hung on a single thread of believability Anakins turn to the Darkside, Lucas messed that one up pretty badly.
