You know since you posted that and some followed up with favorable reviews in addition to "my daughter I didnt give birth to" I watch the first season and I gotta tell you that other than that really cute guy, the son of Katey Sagal, I thought everything about it was worthless. EXCEPT: Katey Sagal. She is incredible in that role. Another case of different stroke for different folks.
Oh and I couldnt possibly narrow it down to one show. Maybe one per genre but not just one.
Comedy - Big Bang
Drama - Law and Order SVU
Sketch Comedy - SNL
This could go on for awhile..........
