I wasn't entirely versed on the Charles Manson murders so this movie was, first of all, terrifyingly eye-opening for me. This is seriously one of the creepiest murders not only in Hollywood history but in American history, and the documentary retells the story in chilling detail with all the gruesome images to accompany it. Yes, the film is historically accurate and educational, but it is also surprisingly edge-of-your-seat and scary! If you're waiting for a calm moment to take that next bite of popcorn, you're going to be waiting a long time (like I was)! I watched this movie with friends for two different movie nights and everyone was successfully creeped out and impressed!! Buy this movie, you won't be disappointed!
