Leonardo DiCaprio does his best with the very weak script. Brad Pitt is boring. Story is dumb. On the whole this is a dumber than dumb film from a dopey director who likes to copycat scenes out of old movies, but does not have the intelligence to write great original stories that formed those original movies. What original scenes there are in 'Once Upon a Time in Hollywood' fall flat splat. The ending, however, is downright ridiculous.
