Quentin Tarantino’s Once Upon a Time in Hollywood is a nostalgic journey back to the Hollywood of fifty years ago. By his own standards, this is a lovingly recreated fairy tale of a Hollywood that is dead and gone. But it is not an exploration of what is true but rather an explanation of what we wish was true. It is an instant classic. People will be talking about this film for a very long time. At 2 hours 41 minutes, you will require stamina to sit through it.
