Listen, I think everyone who has seen La La Land can agree that - while definitely a great movie - it does not deserve so many Oscar nominations.
The story isn’t really anything we haven’t seen before, and the roles aren’t at all demanding. So no, I don’t think neither Emma nor Ryan deserve the Oscar, and the film definitely does not deserve Best Picture.
That being said, perhaps they do deserve Best Cinematography and Best Original Score.
But if it wins Best Picture over Moonlight, Hidden Figures, Fences, Arrival, and Hacksaw Ridge, then that will be absolute bullshit.
