I'm pretty sure they thought "Man, we landed Lizzie McGuire! She's gonna elevate this garbage script we bought." Well guess what bozo!?! She's the very worst part. Yeah, the script is full of terrible dialog and faux-philosphical conversations that mean nothing and accomplish nothing. There is so much bad CGI and most of the time I can't even imagine why they thought they needed to use CGI (They use CGI water when Tate fills up her bathtub, like they couldn't just rig something to put the red dye into the water in a real faucet?). The camera work is very lazy and there are a few very bad shot compositions (Mean Girls boy at the car in the first 20 minutes). The plot is super repetitive and almost pointless. It's a series of vaguely related scenes more than a movie. The title doesn't even really make sense. I guess she's haunted by her "premonitions"? And of course, all of the acting is just awful, but Hillary Duff gets the VIP award for The Haunting of Sharon Tate. She appears to have watched a couple of Sharon Tate interviews and sometimes she tries to gimmick her voice. What we get is Lizzie McGuire randomly going in and out of an unsettling Frankenstein of English Royalty and pretentious hipster accent for the first half of the movie and then she just gives up. I think she keeps forgetting to do the "accent" and the director is just to over it to do another take. All of her emotions are terribly acted and I didn't believe that she was a real human being at any point in the film. I personally don't care about whether or not the film is "respectful" of the actual Sharon Tate's legacy or the seriousness of the Manson Family murders. If Daniel Farrands thinks a Sharon Tate that constantly has premonitions of her death is a neat idea for a movie, than I think he should be able to make that movie. The issue is that he made a very bad movie. Being based on a true story doesn't make the movie better in any way. Really, the only reason to use the Sharon Tate story for the movie is to exploit it. If he wrote a wholly unique story, he'd have the creative freedom to actually utilize his premise. Having a true story as the basis of your movie makes it really hard to add elements, especially supernatural elements. The Haunting of Sharon Tate is honestly just a sad attempt to exploit a series of terrible murders. There is nothing here worth your time. It's not good as a "true story" and it is just awful as a movie.
