The most overrated movie of all time

Rating: 1/10 (13 August 2018)

The headline is pretty much self explanatory. The fact that this movie has won an Oscar is a sign that the Academy Awards' opinion cannot be based on while evaluating movies.
Its pretty much it. I used to respect the Academy Awards' opinion but for the last couple of years, they've pretty much become the People's Choice Awards.
How did this movie win an Oscar?
