Really the only thing I knew about Once Upon A Time in Hollywood was from the trailer. Also, it had something to do with Sharon Tate and the connection to Charles Manson. With the obvious out there, let me tell you in this film you get a perfect glimpse of what Hollywood was like in 1969. Sometimes funny, sometimes weird, and the backbiting made an attack by a werewolf seem tame. Although there are no werewolves in the film. You get a story of both Hollywood as it was and still is to some degree and of an actor and his stunt double/ driver.
The story was great, the plot wonderful, but that ending was totally unexpected and well worth waiting for. I really recommend seeing it.
