What if Lucas felt like he was dealing with too many concepts and three movies would rush them, and decided after TPM to make four or five more films (instead of two more), with the extra films featuring the Clone Wars?
He effectively spaces major events like Anakin’s fall and romance with Padme out over more time, builds up Anakin’s relationship with Obi-Wan and the Jedi more, develops the Jedi, the Jedi Dogma and it’s short comings, and several Masters more, introduces Grevious and several other villains, etc...
Would this have helped or strengthened the movies?
