How the 2 hour and 40 minute runtime is used:
1 hour - Leo acting in random TV shows that serve no purpose to the plot
1 hour - Brad Pitt driving around LA, serving no purpose to the plot
20 minutes - Margot Robbie dancing, watching a movie, and having 3 lines, serving no purpose to the plot
20 minutes - actual plot that I was interested in!
Then the movie ends.
