I'm enjoying the season so far but it does require a massive amount of suspension of disbelief. Sure, no one is going to hear Goliath tromping around on the roof of the house with boots on... I have roofers on my house that are skinny as a rail and I hear them up there.
Also, Duffy's accent is killing me, it's like someone in the UK is trying to do a caricature of an American accent. How the people in charge of Reacher gave that accent a green light is beyond me, it's like nails on a chalkboard.
