I don't think Rey (girl) is related to the previous characters and I kind of hope she isn't. Reusing old story lines like Luke and Annikan being abandoned and not knowing their parents gets old. It was cool with the bad guy being Solos kid.
My biggest annoyance with the film was another death star narrative. Seriously? You did that in episode 4 and then reused it in Jedi which was a bit annoying. Now another one? I will be extremely pissed if the next one has yet another death ray that destroys planets. Seriously come up with a fresh idea!
Carrie Fisher has not aged well. She's listed as 59. She must smoke 5 packs a day since she looked 15 years older.
