Kylo Ren is actually far more annoying than Anakin

Kylo definitely doesn't appear to be all that skilled or even intelligent.

Kylo had family and opportunities afforded to him. He CHOSE to rebel and flee a comfortable life. Anakin chose as well but at least the poorly-written story shows that he had family stripped away from him tragically and, while idiotic, his quest to "save" Padme was rooted in good (if not selfish) intentions.

He was at least given a humane "purpose" for his turning to the dark side, however horrid and misguided the writing was. With Kylo--he was the son of royalty--meaning HE was royalty. His family was on the light side. From what we can gather, he seemed to have the "daddy issues" complex to some extent and also felt "betrayed" by Uncle Luke. They even wrote in a horribly-contrived and out-of-character moment for Luke where he considered killing Kylo.

Anakin's motivations were clear--they were just poorly-written and badly-handled. Kylo's motivations are clear as mud, contrived and erratic.

If you're seriously trying to make the case that the prequels are anything other than garbage, you have your work cut out for you. They plod along toward a foregone conclusion, and rely on the audience knowing what's coming next rather than provide a reason to believe. Each step of the way, the characters change their beliefs and behavior not based on anything in the script, but because it has to be that way. Anakin has to end up evil, so he does. The Jedi have to end up dead, except for Yoda and Obi Wan, so they do. None of it follows any logic, none of it is believable, no reason is given for any of it other than "at the start of Star Wars it was this way, so at the end of the prequels it has to be this way."

They weren't badly written, true, just simplistic and a bit ham fisted.

Now some of the dialogue, though, was atrociously written.
