Golden era of the show..........
I haven't seen literally every episode, but I've seen enough. For me, Season 3 is when the show really comes into its own. Seasons 4 and 5 were excellent. In fact, I think Season 5 had some of the show's best episodes ("Sam's Car," "Double Dump," "Your Grandmother's a Bimbo," "Boozin' Buddies," "Winter Break," "Working Girls"). Season 4 had some great ones as well ("Big Girl on Campus," "A Trip to the Principal," "New Kid in Town," "Car and Driver," "A Farewell to Nick," "Yellow Submarine," "Another Single Parent," "Three Teens and a Tony," "Prom Night II," "Sleep Talk, Sweet Talk"). You know what, scratch that. Season 4 was the best of them all. But Season 5 was still loaded.
I think Season 6 was also pretty good, but I don't think it was part of the golden age. Season 7 was when the show really started to decline, but at least it was right near the end of its run.
So Seasons 3-5 were the golden years. The sweet spot. The peak of the show in plots, humor, characterization, and enjoyment. What about you guys?
