Yes, there are some plot holes and over used tropes, but still an excellent show...
Just set aside any plot holes and just enjoy this novel like dramatization. I think we will be hearing more about this show during award season, too.
Ignore the nitpickers, too.
Kate Winslet did a fabulous acting job and exemplified a world-weary middle-aged person beat down by the world.
And like life, there was just enough humor thrown in that allowed the show not to become a farce.
Plenty of red herrings to keep the viewer interested and good acting all around.
