What ?
This is so blatantly wrong I am not even sure where to start here.
We saw Anakin as a child, how he came late into the jedi order, had to leave his mother behind on a trash planet, how he started falling in love which was prohibited, finding his mother was sold and tortured then ultimately killed, we saw Anakin actually doing amazing and impressive things, showing his potential and growth over the films, his relation with the dark side after the loss of his mother, his feelings that were not contained, Palpatine exploiting his weakness, the fear of losing his loved one, what he was willing to sacrifice etc...
What the fuck did we get for Kylo that is anywhere near that ?
"Oh boo woo the light side is seducing me" "I am torn inside" "Join me !"
As he stands, he is a moronic ungrateful brat who can't make up his mind, throws tantrum every two seconds, and gets bested in force control and lightsaber duel (while wounded) against a girl who literally awakened her powers 5 minutes ago. He looks like a child, acts like a child, and we don't even know anything about why he's doing it, you can't possibly say the guy is more developed than the whole Vader story arc.
He might (and we all hope he will) be much more in the sequels when they elaborate on his backstory, and try to redeem him.
