I do like the movie.. Joel is an interesting man as monsterous as he is... The objectivity of how he as a person developed down the line into who we know Joel as is incredibly well done.. Very often the story is told to emphasize the dramatic perception that they just ARE monsters.. not they end up the monsters we know when they're caught... I have one major major criticism... The narrator/actor is portraying Joel Rifkin the person in first person.. not a character, and not reading a manuscript of his interviews.. He needed to BECOME Joel.. He IS the New York Ripper... And this actor just simply read as generic person X. Joel has a way of talking, and importantly his NY accent... that's a part of who he is... You miss a lot neglecting to add those details.. attitude, tone, showing lack value of the lives he took, the sense of his inner battle trying to convey his actions in an understandable way with no understanding himself.. Whether actor or director.. that was a big fail... it's hard to hear the narration in this movie in that bland young guys voice and tone and try to dive into Joel's mind and ride through that mental battleground of a person he was.... That voice did not sound like it had any relation to what was playing on screen.. It pulled you into the story about as much as an entry level job's employee training video does..
If your interest is the visual representation of real life Joel's actions.. this movie is great... but if you wanted to not only know what he did, but also dive into their dark minds to try to connect and understand it. this isn't that...
