Admirable film.

If the ambition is to provide two hours of instantly forgettable, popcorn-munching escapism, it succeeds.

The film never slows down or bores, plunging from one harrowing sequence to the next.

The movie turns out to be a little better than the average. Starting from a romantic formula often seen in the cinema, it ends in the most predictable (and somewhat bland) way.

... in a hunt for truth. i do not understand the critique i have read so far. anyone with common sense won't expect to be served with a clear solution and hard evidence. decades went by, evidence got destroyed or lost.i really liked the authentic interaction and presentation of the obsession, on Cameron's side to really connect all the dots he found, and confusion and longing for answers about himself, on Wayne's side ( fear of 'having the killer-gene', afraid of having inherited some of his grandfather's psychology ) it follows their quest from station to station of Cameron's almost decade long research. at ep 3 and 4 one can see how far down the rabbit hole Cameron is ... he is obsessed with 'the whole picture' and of course exonerating where exoneration is due. - and i can understand how the viewer (& Wayne!) gets frustrated (when he expects clear judgemental material) but this is no Nancy-show and the reality has gradients. in the last episodes they get to phil stanford which again serves as a milestone in their journey.. so i would say it really pays to stick with them. you can feel Cameron's pain and misery, I mean ...just imagine being a detective & being so dedicated ... and the years and sacrifices he made. it makes me feel good. it gives me hope to see that such people exist... and to see that law enforcement is so uncommunicative really angers me.. especially with the last bit when it's about hard evidence.i am sincerely recommending this for anyone not judgemental, interested in crime, psychology & people in general... (and of course the 'system')( - oh.. one thing i really missed is a visual timeline )

I liked idea of this and it is something worth looking at, but the main investigator is nuts. He uses terrible links and theories to connect murders. He didn't like his mom and she had dark hair so he killed dark haired women. It's a bit ridiculous. I bet he killed Marilyn Sheppard. She has dark hair and her husband was framed. Just that connection would make this guy be convinced it was Ed Edwards. He may be the Zodiac, but all those other major crimes are an extreme stretch.

I believe, like Edward Wayne Edwards' daughter, April, that her father is the Zodiac Killer, and that he may have committed other crimes where he mimicked the Lipstick Murders of 1945 and 1946. He also may have been obsessed with the Black Dahlia murder, but he is not responsible for the Lipstick Murders or the Black Dahlia murder. If the crime involved cryptic notes or taunting the press, police or families with letters, then Edwards may have been the perpetrator. Or, in the least, he may have tried to frame innocent people for high profile crimes by misleading police with anonymous tips and letters.John Cameron's intentions are pure but his confirmation bias is clouding his judgement.I like both John and Wayne. Their relationship is compelling, and the series, "It Was Him," is very well produced.

First of all, straight off the bat, I'd like to say I like John Cameron. I don't think he's in this for money or fame, but rather, through some sort of traumatisation. I remember him well from the episode "Misery" in "Real Detective", and in watching that, and seeing how committed to that case, the guy basically lost his family. This series (after episode 3) just gives off the vibes of a man with nothing left to do with his time but try and help others, even if he is usually more of a hindrance than a help.People don't want to talk to him as it's like they've heard rumours of a crazy man who thinks that the same person who done the Black Daliah murder was also The Zodiac AND killed JonBenet. And the sad thing is, he seems to be unintentionally sucking young Wayne into his crazy way of thinking and there is no person on the other side of these insane accusations who could spread some rational thinking on all of this.I'm interested to see where the remainder of the series goes, but really, for now, all I want is Wayne to be able to take a step back and have a serious think about all these bizarre suggestions, and for John to seek some help.
