That seemed to be a trend during that era of TV. The protagonist has a problem, spends the whole season solving that problem, and then discovers that they have created an even bigger problem in the season finale. Repeat until your show about “regular person in a tough situation” slowly turns into “person with barely enough luck to survive kills God”
One of my favorite shows of all time. The jokes are non stop. Many are in-your-face slapstick, but others are subtly slid into the dialogue. It’s a smart comedy about stupid people. I consistently found myself hoping that everything would work out for this bunch of morons, but at the same time, laughed when they got what they deserved.
