George Lucas could have taken the most important events of the Anakin trilogy and turn them into flashbacks to be placed in Return of the Jedi to reveal Darth Vader's past as the showdown with his son draws near.
I have no problem with there being films showing the adventures of Anakin and Obi Wan, but why did they have to be so bland and predictable? Why did they basically connect points A to B, and exist only to set up the original trilogy?
These films should have had a story that could exist independent of the OT, and had some surprises for the audience. Other than Midichorians.
