This review will not contain spoilers (not more than the blatantly obvious spoilers of official movie trailers they make these days) but some of my reflections may reveal some elements of surprise (there aren't that many surprises though in this movie that has practically no plot), but anyway if you want to stop reading now before you start whining about spoilers, then do stop. For the rest who continued reading: why change the history of the events? (i.e. The murder of Sharon Tate by the Mason family?) what is the purpose? I could accept it if it were portrait as some sort of a sci-fi parallel timeline type of thing, but as presented here like a normal story, it just doesn't make any sense and is actually rather childish and off-putting.
