I tend to be always wary of things based on a true story. A mixture of fact and fiction often blurs the tedious factual parts with outlandish falsehoods to make the show more exciting as a whole. Therefore it can often be difficult to engage yourself to view it as fact as there are a large number of scenes which appear to be grandstanding for the viewers.
Despite the above, the series is actually an exciting drama with some occasional comedy moments. It's certainly worth a viewing. The acting itself appears great, however it's difficult to know how good the acting is considering we're unaware whether the actors are portraying the Ingrams directly or whether there have been things added.
The reason for the 7/10 is not due to the production, excitement or directing, it is due to the script. I am slightly perplexed as to why the script has been written to feel empathy towards Charles Ingram. Although the wife was responsible for pushing Charles, he has surprisingly been made to look the innocent party, this is despite Charles committing insurance fraud before the quiz show fraud. So why has the script been written to make us feel empathetic?
Overall the show is well worth the watch. It's exciting, gripping and interesting. Would really recommend, however most certainly take everything with a pinch of salt - it's not all fact!
