I do not understand

Rating: Null/10 (29 June 2018)

Disney has money. Disney has lots of money. Why didn't they hire a good director and good actors? Why do they bring inferior amateurs to film and play in Star Wars?
Could someone explain this to me?
Also, whya re they remaking and yet calling it a new episode. It is so confusing that the rebels won and now they are rebels again.
Could someone tell me?
