Kylo Ren, while his story is very similar to Darth Vader’s, is one of the greatest villains of all time and the best Star Wars villain.
Urge to drink … rising.
To be fair, I would’ve said that Kylo was the second best Star Wars villain if the prequels didn’t thoroughly ruin Vader.
Some other tips :
Avoid politics. The original Star Wars wasn’t really WW2 in space. The Empire was just based on the Nazis but also the British during the American Revolution (why all the grey shirts have British accents). Star Wars is more like the American Revolution in space not WW2 and this isn’t explained through dialogue. We know this from the very first shot of the original Star Wars. Keep the politics simple and visual. You didn’t hear any talk of space taxes in the original trilogy.
Sadly, the prequels are still canon. Any Jedi character more skilled than a Padawan is probably going to be an emotionless robot IF there is a Jedi Order. It doesn’t even make sense that there would be a succesful Jedi Order since Luke did not finish his training even after Return of the Jedi. Work around the prequels.
I actually enjoyed the prequels in spite of Jar Jar’s annoying presence and Anakin’s unlikability. At least the prequels were original even if the execution was wanting in many respects.
I am still surprised that you prefer Kylo Ren to Darth Vader. Kylo Ren is essentially the bipolar Anakin Skywalker from Attack of the Clones only less skilled in combat.
At least when Anakin complained about Obi-Wan and lashed out in anger after his mother’s death I could understand the source of his anger and empathize with him.
After Anakin’s transformation to the dark side, he massacred children in a heartbeat - no questions asked. Kylo Ren struggles to be evil. He is the weakest villain in the history of weak villains. Rey utterly defeats him the first time she wields a lightsaber. Compare this to Darth Vader defeating his own son and cutting off his hand in The Empire Strikes Back.
Any of the villains from Prequel Trilogy - Darth Sidious, Darth Maul, Count Dooku, Jango Fett, General Grievous, Darth Vader, or even the Neimoidians - would be more menacing than Kylo Ren.
Kylo Ren is a bipolar emo goth copycat killer with granddaddy issues who wears a mask for funsies. He is the weakest villain of any story from any culture in the history of literature.
