I enjoy the middle of the series most. That's when it hit its stride in my own opinion.

I agree, I think it was the best during the middle of the series. I don't think I can narrow it down to one favorite.. I'd say my favorites are 5 and 6.

I love the middle seasons, too, because the main cast was finally settled and creator Reinhold Weege was still with the show as executive producer. I swear, when Chris Cluess and Stu Kreisman took over, it became almost cartoony, even though Cluess and Kreisman had previously done some very high brow writing on SCTV Network 90.
