Understand that while I much prefer the OT, I can watch (and enjoy to an extent) the PT. I’m probably not alone in thinking that there were elements missing from the PT which would have made it better.
Here’s a small list:
An angry, ill-tempered Darth Maul. For a young Sith apprentice, he sure was composed and serene. Why wouldn’t he be bubbling cauldron of anger?
Episode I - Anakin at 19-20 years old. As millions of fans have observed many times.
Anakin sparring with Obi-Wan. Lucas loves the obvious foreshadowing - why not this?
Anything else?
