It’s silly, but addictive. Silly because there are too many plot gaps and coincidences — too much suspension of disbelief is necessary. But still fun....
One thing, though. Someone who speaks as precisely as Mr Reddington would not make a grammatical error like “...for Lizzy and I” when “for Lizzy and me” would be correct (I caught it twice), nor would he say “Cartagenya” when he meant Cartagena.
