The best duels are ones where the duelists have some major personal history and backstory that led to the duel happening in the first place. That’s why the duels in ESB and ROTJ are always the best. In ESB, you have Luke fighting the man who killed his father (or so he believes), and in ROTJ you have a son fighting his own father. Only the duel in Revenge of the Sith, where you had a former student fighting his former mentor and friend, even had the potential to surpass the Luke/Vader duels. But unfortunately, since the Prequel movies failed to establish a compelling relationship between Anakin and Obi-Wan, the duel itself is just empty and over-compensates with CGI lava effects and John Williams.
I mean, John Williams could score anything and it would be awesome. A movie scene showing somebody doing their taxes set to a John Williams score would be amazing. Let’s call it “Tax Season II: The Accounting Begins”, with music by John Williams.
