Fantastic conclusion, Obi Wan had animie style powers towards the end, animated clones wars stuff, it's like they went out of their way to show he was more powerful than Rey.
Still can't seem to kill Vader though, but then that was never going to happen.
The smashed mask was a nice touch, it felt like he really connected with the old Anakin for a second there.
It was in interesting choice at what could have been Vader's death, he let Obi Wan know he didn't fail him. To give his old master some sense of peace.
Owen and Beru did great in the fight with Reva, Owens line about Luke being his destroyed me.
Some nice cameos towards the end.
