He's 30yo man who acts like an edgy teenager, he doesn't even have reasons to be on the dark side. He just blindly follow the path of his grandfather like a bitch without his own opinion. None of the characters in sequels are worthy remembering. There is:
>white woman who can do anything
>nigger le comic relief
>latino guy eye candy
>asian FAT woman
>purple haired lesbian who is in charge of everything and dies a hero way (JESUS FUCKING CHRIST HOW THEY MISSED THE OPPORTUNITY TO KILL ACKBAR THIS WAY)
>superpowerful bald deformed guy who dies like a fag
and actually Rey is the most likeable one but making her the most powerful jedi of all time was superdumb and completely destroyed her character
