Elements of a period-piece Entourage and Californication (but without the gratuitous sex) help capture the 'carpe diem' lifestyle of Hollywood in the middle of the mood-change from the 60s to the 70s. Hard to tell exactly who is the lead actor (true co-stars) but that is just one intriguing aspect of the screenplay. The parallel story lines touch and separate a little haphazardly but not enough to interrupt your concentration and enjoyment over 150+ minutes. I actually thought Margot Robbie stole the 'best actor' award for her portrayal of a beautiful but somewhat naive and child-like Sharon Tate... and the mini skirts didn't hurt. This is a movie that requires a good (and lengthy) memory, or quite some knowledge of 1969 news and culture, to be fully appreciated. I think many under 50s will appreciate a second viewing after boning-up on The Manson Family, Polanski/Tate, Steve McQueen, Spaghetti Westerns, etc. Well worth ticket on a big screen - not least for the after film debate with friends/family. Of the Tarantino portfolio this one will spark as much discussion as any. Brain-candy!
