Felicity Jones is way too beautiful compared to Daisy Ridley.
Judy Garland was way too beautiful compared to Liza Minnelli. What’s your point?
In the inner logic of movies you have to buy a slight ressemblance between relatives. I don’t see any between Jones and Ridley.
edit: but with second thoughts, Portman and Christensen are way better looking than Fisher and Hamill, so… wouldn’t be new in SW.
