This is definitely a fantastic show. Having never read the book I don't have anything to judge it in that regard but the massively brilliant Brendon Gleeson was a stroke of casting genius as is the part of Mr Mercedes himself played equally brilliantly by Harry Treadaway (Fans of Penny Dreadful will recognize and agree). The story is solid and engaging and feels as though it could be real which is what makes a great story. Full marks for Mr Mercedes.
This is a thriller show about a guy that used to be a cop, and a few years after retirement he gets haunted by the attacker of one of his cold cases: someone who drove a Mercedes over a dozen of people and ran way
A lot of suspense is expected and curious to see how the show will take from pilot episode. 4 out of 5 for now.
