I just finished watching the last episode, "Day Five." Whoa! Completely gut wrenching, harrowing, brilliant and extremely disturbing. Season three, even though it was only over five nights, was fantastic, IMO.
I do hope there will be a fourth season. I want MORE, MORE, MORE!!! If the series continues, I hope they can include Lois, Mrs. Spears, Johnson (scary woman!!), and Mr. Dekker, even as minor characters. Oh, yes-PC Andy as well. He "done good" tonight.
Of course I want Gwen and Jack back, with Rhys, too.
