They did 7 seasons of mixed adventures (amazing, but declining as time went on, still good tho), then Archer was in a coma for 3 seasons for plot reasons so we had the Coma Years™ which weren't great.., then it was back to 'normal' when Archer woke up (but obviously not as great as the original few seasons), but a return to form. Final season just finished days ago (haven't watched it yet myself).
