George Lucas takes a lot of unfair heat for changing his Star Wars
films over the years. They are his films, he's allowed to. When you
grow as a filmmaker, you sometimes have the desire to improve your
previous works. Correct continuity errors and plots holes. Maybe add
back in a scene that was previously cut or reshoot a specific sequence.
There's nothing wrong with that. And Lucas isn't the only one that has
done that either. Other directors are doing it all the time. I am in
the process of recutting and improving my older films and I am enjoying
the experience.
