I think the show is fantastic. I will binge my way through it.
However, I think the script doctors ought to be more careful about tiny details. In the first season, I caught two LAisms without even trying.
After living in both Chicago and LA, I know that freeways are numbers in LA and are named in Chicago -- no Chicagoan would be caught dead calling calling the Eisenhower freeway the 290.
Chicagoans have 'Fannie Mae' chocolates not 'Sees'.
Script writers beware -- some of us have lived in both places.
