YMMV / Charlie Says

• Complete Monster: Charles Manson is a narcissistic cult leader with messianic delusions. Using his charisma to charm impressionable young people into following him, Manson is controlling and possessive, and keeps his "family" in line with regular emotional, physical, and sexual abuse. Intending to sic his followers on a record producer who'd previously declined to sign him to a label, Manson instead has them murder the home's new occupants when he learns that the man has moved away. Six people die in this attack, including a pregnant woman and her unborn baby, followed by two more in an additional attack Manson orders. Manson instructs his followers to make the killings look like hate crimes perpetrated by black people in order to kickstart a race war that would destroy civilization and ultimately see him ruling over black people, whom he sees as being incapable of creating a functioning society. A master manipulator, Manson's hold on his followers is so strong that they remain brainwashed even after being separated from him in prison, and when they eventually realize that Manson's "revolution" was nothing but a sham, they are mentally broken by what they have done.
• Hilarious in Hindsight: Perhaps not hilarious exactly, but this wouldn't be the last time Matt Smith played an abusive man in the 1960s... only the next time, he'd be doing it on the other side of the pond.
