Where to start? Something nasty happened in the woodshed 16 years ago. That one event defined all the characters involved, no one moved on, evolved, or processed those events. The events described are not particularly nasty, Jedis under attack inadvertently kill their attackers, So they all go hang themselves out of guilt while the others enjoy a little naked hot sith action. Zero mystery, perverse tone. Somebody put a walking green plank in charge and no one knows why. That's how paper thin this story is.
Whatever hope and joy one once got from the original trilogy is completely sucked dry. The only character who seems to like anyone and could grow up into a recognizable jedi gets a quick three stab throw away death. If the showrunner wanted to create Russian doll in space (without any humor), that's fine, just don't call it star wars.
