Don't listen to the negative reviews

This movie was so-so. It had it's moments, but wasn't the greatest.

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

It's simply great fun, a winsome film and an occasionally over-the-top luxury fantasy that never flags.

... 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 don't doubt that Cameron believes All he says, but he seems to want to attribute far too many unsolved (and some solved) murders to one man. I could possibly believe Edwards could have murdered far more people than he admits to, but trying to make him the Zodiackiller and the killer of Jon Benet Ramsey AND Lacy Peterson AND list long litany of crimes nationwide just seems forced.I don't buy that just because there was some overlap with Edwards' MO and other killers is far from conclusive.

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.
