The originals are schlock by today's standards, but what they were competing against when they came out was unadulterated trash.

You can see the actors fighting their hardest against Lucas' directorship to make the prequels good. The prequels are not good. The main redemption of the prequels is the glut of CGI developments that came about as a result.

Rogue One is great. Solo is not great and probably killed other independent films in the setting.

The sequels are just bad.
