Gregg's life turn upside down. Will he marry or not? How can he take care of his three children alone without a woman, but he is also sad, so he does not know what happened to his wife.
Christopher Eccleston clearly can't put in a performance that's anything less than towering, even when you spend the first five minutes trying to adjust to his Belfast accent.
It's possible that the handsome Greg, and his ex for that matter, will confound the odds, and that's why I'll be watching the next episodes. There may be lessons there for all of us, sooner or later.
