We loved that series! We binge watched it, and just like when finishing a great book, were sad to see it end.
It had an excellent ending although we knew “John” would not make it through the last challenge.
I’ve binge-watched the complete series 3x...and expect I’ll watch it again...soon.
Fun fact...
John Nolan, who played “John Greer” is the uncle of series creator, Jonathan Nolan.
