Few comments on Once Upon a Time in Hollywood

The Oscars aren't about logic; it's more about strategies to get as many awards for a film as possible, so the categories are kept vague. DiCaprio was nominated for Best Actor (mediocre performance, but he's a big name and a previous winner, so now he's a Big Star and has to be nominated, just like Streep almost always gets a nomination for her show-off performances), which means Pitt can't be nominated for Best Actor for the same movie because they'll cancel each other out.
