I couldn't agree more with William Dickey and RMS1949. I found this on Streampix this morning and thought I'd watch it before I had to begin my workday.
Mary Brunner turned into a blonde, Linda Kasabian turned into a brunette, the only requirement for Susan Atkins appeared to be the ability to make bug-eyes and a weird-looking smile (which seems to be the ONLY idea of indicating "crazy" that "filmmakers" can think of) and you'll find better acting skills in a kindergarten operetta - so I think Mr. Dickey hit their casting process on the head. (Too bad something else didn't get hit on the head before this waste of time was filmed.)
As for the storyline: Jay Sebring and Sharon Tate hear the shots that killed Steven Parent, when police tests showed that not even William Garretson could hear them in the caretaker's cottage? The screenwriters were even incorrect about how pregnant Sharon Tate was; they had Rosemary LaBianca say to her husband as she reads the newspaper, "That poor girl She was seven months pregnant." (Tate was 8.5 months pregnant.) In case the reader thinks I'm nitpicking, I'm not. These were the two least-bad parts of the movie. The rest of the movie goes into a blur of bad.
RMS1949's evaluation summary was perfect: "Total garbage." I will add that this garbage is so rotten that even the Manson girls would pass it up when they went dumpster-diving for ingredients for dinner.
The producer and any investors would've done better to have given the money to Michael Cohen to pay off one or two of Donald Trump's many companions - and then checked themselves into whatever kind of rehab helps clear film professionals' dulled evaluation skills.
I sat through a Strawberry Shortcake movie, a Care Bears movie and "Drop Dead Fred" with my child while she was growing up because I love her, but "House of Manson" makes those three look like Oscar-winning classics.
