Seasons 4-6 where peak
Seasons 4, 5, and 6 were the best seasons. Usually shows decline in quality after season 4, but Archer was truthfully peak season 4 to 6. Season 4 has so many great and rewatchable stand alone episodes (Legs, Midnight Ron, Once Bitten, the Papal Chase). Season 5 is one of the best seasons in general. It was great seeing them go from spies to drug dealers and how they're even worse at the later. We all also love Pam the Coky Monster. Season 6 was great seeing them going back to being spies and also had plenty of great stand alones (the Archer Sanction, Edie's Wedding, Vision Quest, Sitting, Drastic Voyage)
