I am sure that they have been mentioned here before, but both Narcos and Narcos : Mexico are first-rate.
The first few episodes of Season 1 of the former are not all that distinguished (though the reference to 'magic realism' in the narration that accompanies the very first one gives a hint of what is come).
However, once it gets into its stride this series and its sequel are right up there with the very greatest TV dramas in my view, and what is extraordinary is that much of what transpires happened for real, apparently, or at least that's what my nephew told me), especially when it comes to some incidents for which you might have to suspend disbelief were they to be featured in an entirely fictional drama.
