God, this episode was a real let down compared to the first 2, and episode 2 was a let down compared to episode 1, so that does not bode well.
Nesbitt's character was annoying beyond belief, even before he saw his wife he was acting like a total moron. There's a frigging nuclear reactor about to go critical and he's looking at pictures of his wife, and for some completely incomprehensible reason ignoring fervent and urgent calls from his team, who are all sat on top on the nuclear reactor. What, too much effort just to say one word so they know he's not dead??
Terrible. At least he's found his bloody wife now, so maybe he can stop acting like such a twat.
