Of course not. Star Wars (1977) saved movies. Up to then, the 70s produced the dreariest, most depressing sci fi.
Star Wars Episodes 1-3 ruined movies...and Star Wars.
In the 1940’s and 1950’s they had ‘Film Noire’.
In the late 1960’s and into the 1980’s they had what I call, ‘The Theater of Despair’.
I call it that because almost every movie out of that ~20 year period has an ending where everyone dies, the world ends, the bad guys win, and at the end there’s no hope.
‘Rogue One’ was all about hope, sacrifice, honor, nobility, and above all: redemption.
No way Hollywood would have allowed that kind of film in the Despair period.
