Lucas reminds us of his early inspirations— Flash Gordon , Commander Cody , Tarzan , King Kong , Frankenstein , and (again) the oeuvre of Ray Harryhausen—but also alludes to Biblical and Greek Tragic conundrums, Faust , and buddy Francis Ford Coppola's The Godfather .
I was intrigued by the relationship between Obi-Wan and Anakin, I cared about the deaths of the Jedi in a long sequence that was very reminiscent of “The Godfather”, and I hoped Anakin would make the right decision despite the fact I already know which path he chooses.
Lucas takes a note from The Godfather in a montage of Jedi knights falling victim to traps (a sequence that would have carried much more weight if only viewers had come to know these Jedi, see them in their full glory, and comprehend the pain of their downfall).
Beginning with Anakin’s fateful decision to the cold, emotion-stirring Clone betrayal with Order 66 to The Godfather -influenced proclamation of The Empire intercut with Anakin’s slaughter of the Separtists, Sith takes a heavy, emotional turn.
