Not to mention they ruined two big things.
The force, which was this mystical magical ESP like shit, basically being explained by bullshit science, and used like the freaking holy spirit,
And Darth Vader's mysteriousness. All we knew was he was a Jedi that was "seduced by the dark side", and as time went on, we learned that he somehow paid dearly for it with being trapped within his armor. He was literally a black knight. And he redeemed himself.
So he was a Space Samurai, who became a Black Knight, who got a Viking funeral.
Come on. Thats badass.
Then they made him an emo jerk with zilch emotion and anger management issues.
Come on Lucas. your neck has already been swallowed up far enough. MUST you make it be swallowed further by your chin with your love of special effects over quality writing?
I also was not a fan of replacing the original "force ghost" of Vader with Hayden Christensen. "oooh but he appears the way he was before he went to the dark side!"
bull shit. He redeemed himself at the end, he should look like he did, but un-burned.
