Having never watched a minute of this until last Monday I've skelped through 5 seasons in about 8 days before this. It's very good, if a bit nonsense at times.
Nearly pissed myself laughing when Fleming turned into John Wick at the end of season 3. Sprints about 3 miles at full pelt wearing a bullet proof vest and an assault rifle then perfectly snipes the driver of a speeding vehicle off a bridge from about half a mile away.
