I have definitely heard that accent from people I work with (over the phone) in Wisconson, you betcha. Not all residents have it to the same degree.
The pacing was a little slow in the beginning - but that is probably to be expected in initial episodes. When we don't know the characters yet, those 'meaningful stares' don't carry the meaning to the audience. It was enjoyable - I will tune in again next week.
...and STAY out of the WOOLWORTH's!!!!!!!!!
