Yup. I get it needs to be Aaron Pierre's show, and by the end I liked John enough for that to work, but you gotta figure out a way to have some Kyle Chandler in s2.
I do have to say, British actors are lucky that Americans don't have a great ear for regional accents and even if something sounds off are generally willing to assume someone moved around as a kid. Pierre somewhat, but also Bumblebee Homerdome and Hugh Laurie.
