And Han and Leia just have to be divorced? Ok.
And their son just has to be evil. ... Ok.
I didn't even bother watching the last film so I don't know if Kylo has his own fun little redemption arc too or not, but no thank you.
Yes; Luke never really dealt with betrayal. He only ever knew Darth Vader, so he wasn't betrayed by Anakin the way Obi-wan and Yoda were.
> And Han and Leia just have to be divorced? Ok.
Your son switching over to the side of the people who blew up your home planet would put a strain on any marriage.
> And their son just has to be evil. ... Ok. I'm actually with you on this one; Anakin's final transformation to Darth Vader was rushed, but at least the seeds were there from episode 1. As far as I remember, Kylo just turned evil because the Force wanted him to.
In the sequels he plans on doing nothing for anyone (especially his friends) and doesn’t believe in his nephew.
