Below are comments that could amount to a review by a fellow activist who saw that documentary.
Peter Rodger = excellent camera work/photography/locations/variety of interviewees but predictably anti-religious.
Elliot Rodger had very little chance to get sound morals from his father. Peter did a whole doc. on "God" w/- basically ignored morals!
What is supported in that doc. = very vague New Age "we are all God" "be yourself", organized religion sucks mumbo jumbo.
Jews = barely discussed, Muslims = most are violent, Catholics = sexually repressed, & official. organized rel. causes wars/violence.
It must have taken years to make that documentary - time better taken w/- looking after his son morally!
