I love this show
Yes.... it is the same thing over and over again. Bev goes too far smothering her kids, then she realizes it and apologizes, then everyone hugs at the end.
But wasn't that also true for all of the great sitcoms? I love Lucy, The Honeymooners, Golden Girls. Gilligan's Island, Betwitched, and even Seinfeld were all "formula shows."
What makes this show great boils down to three things:
1. Great writing
2. Great acting
3. Great attention to detail
