In A New Hope, Vader is a former pupil of Obi-Wan’s who turned to evil and hunted down and destroyed the Jedi Knights, is a great and powerful warrior, is a religious mystic, and is a TIE-Fighter pilot.

Darth Vader is a traitor, a warrior, a mystic, a pilot, and a cyborg. That is hardly one dimensional.

What in the hell does most of that have to do with distinguishable personality traits that makes someone a 3 dimensional character or villain? Other than being evil Darth Vader in STAR WARS exhibits no other personality traits and that makes him one dimensional.

Imagine if Darth Vader took off his mask, spoke of his struggle between the light and the dark sides of the Force, and struggled to kill Obi-Wan, who was a father figure to him. He would have been a much weaker villain. Villains should not have to struggle to commit villainy. Villains should be naturally villainous.

The difference is that Vader at that point had 19 years of being a Sith Lord so of course he wouldn’t have the same conflict. Kylo on the other hand hasn’t even completed his training and has only a few years as a Dark Sider; it’s unfair to compare the two. Now if Kylo Ren shows this same kind of behavior once he fully immerses himself in the Dark Side, completes his training and has more experience then you’ll have a point. Also killing a father figure who you despise and who maimed you is different than killing your actual father who you have mixed feelings about.

I thought that this quote would be a nice addition

“The saber itself is a big metaphor for the character – it’s unpolished and unfinished, and you may or may not get the sense that it may not work at any given moment.”- Adam Driver

The scene in which Kylo Ren struggles to murder Han Solo was supposed to be poignant. In reality, it was pathetic.

I can say the same of the scene in which Anakin cuts off Mace’s hand and all.
