I was a hard core staunch believer that the McCanns had accidentally killed their daughter and covered it up. I had read the book, The Truth of the Lie, and I read case files found on the internet. I also watched lots of YouTube documentaries on how to tell when people are lying and how Gerry McCann was a great example of a liar, which compounded my opinion. I was convinced. They did it!
However now, after watching this Netflix documentary I'm not so sure. Other reviews are critizing this saying there's nothing new being said but that's simply not true. There are episodes that go into what the private dectectives found and uncovered that I would suspect most people didn't know about, etc.
So yes there will be new information you'll learn. Will it be a lot? Probably doubtful as it's been such a high profile case for over a decade, however the information I found interesting was enough to make me question my personal opinions.
Is there a conclusion? Of course not. We all know that. So people complaining about that aspect need to get real!
I do agree however that this could have been a much shorter documentary. They definitely dragged it out way too long. But if you're interested in the case then you'll watch it.
