Ranking the Seasons

Just began this series after meaning to for years. Is your ranking worst to best or vice versa? Almost done with season one. I knew the general premise that the husband and wife were deep cover Russian operatives but I never knew how good or bad they were. I was kind of hoping to root for them but they may have crossed certain lines already (Kerri R killing the security guard and Mathew R killing the FBI agent). Also just want to point out Noah Emmerich was perfectly cast in the role. I saw his character break bad executing the Russian diplomat so I wonder where that will take things. It's a big commitment but I think I'm in for a treat.
